RV storage on Grand Island gives you something most WNY storage options don’t: central location between Buffalo and Niagara Falls, easy I-190 access from Exit 18A or 19, and the lowest starting price in the Jeff’s Attic system at $75 a month. The right unit size depends on what you’re storing. And not every RV fits in a standard self-storage unit.
This guide covers exactly which RV types fit in indoor storage at Jeff’s Attic Grand Island, the current 2026 unit prices direct from the location, what to do to your RV before WNY winter sets in, and how to reserve a unit before camping season ends.
RV Storage on Grand Island: What Jeff’s Attic Offers
Jeff’s Attic offers RV storage at its Grand Island, NY facility at 1763 Baseline Road, with indoor unit sizes ranging from 5×5 up to 20×30 and starting prices from $75 per month. Class B campervans, smaller Class C motorhomes, travel trailers under 30 feet, pop-ups, and smaller fifth wheels fit in indoor units. The location offers 24/7 access with no appointments required, and a 10% military discount that stacks on top of any current promotion.
For larger Class A motorhomes (30 to 45 feet) and fifth wheels over 30 feet, indoor storage at Grand Island won’t fit. Call (716) 773-2000 for outdoor or oversized storage options.

Why Grand Island Works for WNY RV Storage
Grand Island sits in the Niagara River between Buffalo and Niagara Falls, traversed by I-190. For RV owners across WNY, that location matters for three practical reasons.
Central location
From Buffalo, you’re on the South Grand Island Bridge in 15 minutes off I-190. From Niagara Falls, you’re crossing the North Grand Island Bridge in about the same time. Grand Island is the geographic middle of WNY’s RV-owning population.
Toll structure works in your favor
The two Grand Island bridges only charge tolls in one direction each: northbound on the South Bridge (entering the island from Buffalo) and southbound on the North Bridge (entering from Niagara Falls). Your trip TO storage costs an E-ZPass toll. Your trip home from storage doesn’t. Over a season of trips to swap gear, that adds up.
Camping access matches storage location
Grand Island and the immediate area host several major campgrounds: Niagara Falls/Grand Island KOA, HTR Niagara Campground & Resort, and Cinderella Motel & Campground. Beaver Island State Park is on the south end of the island. Buckhorn Island State Park is on the north end. If you’re storing here, you’re already where you camp most weekends.

| 10×5 | $95 | Same footprint as 5×10, different layout |
| 10×10 | $130 | Pop-up camper (folded), motorcycle plus gear |

The lowest price in the Jeff’s Attic system starts here at $75 per month for the 5×5. For RV owners specifically, the 9×25, 10×30, and 12×20 are the practical sizes. Picking the right one depends on your RV’s exterior length plus 2 feet of clearance for backing in and closing the door behind you.
Which RV Types Fit in Standard Indoor Storage
Self-storage units have a door height limit of about 8 to 10 feet. That cuts out the largest RVs, which can stand 13 to 14 feet tall. Here’s how it shakes out by class for vehicle storage at Grand Island.
Class B campervans: Yes
Class B vans run 17 to 22 feet long with heights of 8 to 9.5 feet. The 10×20, 9×25, or 12×20 units handle Class B vans comfortably. These are the easiest RVs to store indoors.
Class C motorhomes: Mostly yes
Class C runs 20 to 32 feet, with heights typically 10 to 11 feet. The 10×30 unit ($230/mo) fits Class C motorhomes up to about 28 feet. Larger Class C rigs (29 to 32 feet) need the 20×30 ($400/mo) or call to confirm.
Class A motorhomes: No
Class A motorhomes run 30 to 45 feet long and 13 to 14 feet tall. They will not fit in any standard indoor self-storage unit at Grand Island or anywhere else. For Class A, you need an outdoor parking space, a covered awning lot, or a specialized RV storage facility with oversized indoor units. Call (716) 773-2000 to ask about outdoor space availability.
Travel trailers: Most fit
Travel trailers range from 12 to 35 feet. Anything under 28 feet fits in the 10×30 indoor unit. Smaller trailers (under 23 feet) fit in the 9×25 or 12×20. The largest travel trailers (32 to 35 feet) won’t fit indoors.
Fifth wheels: Smaller ones only
Fifth wheels run 22 to 40+ feet. The shorter end fits in the 10×30 or 20×30. Larger fifth wheels (over 30 feet) need outdoor or oversized space.
Pop-ups and teardrops: Anything works
Pop-up campers fold to about 5.5 feet tall and 8 to 16 feet long. Teardrop trailers run 8 to 14 feet. Either fits in a 10×10 or 10×15. These are the cheapest RVs to store at Grand Island.
If you’re between sizes, take the bigger one. Backing a 26-foot travel trailer into a 25-foot unit and trying to close the door is the kind of mistake people only make once.
How to Prep Your RV for WNY Winter Storage
WNY winter takes RV plumbing apart if you don’t prep it right. RV water lines start to freeze when temperatures drop below 30°F for more than 30 minutes, and Grand Island sees plenty of that from late October through March.
Here’s the standard winterization checklist:
- Empty black and gray water tanks at an approved dump station. Both KOA Grand Island and Cinderella Campground have dump stations.
- Drain the freshwater tank. Open the drain valve, let it empty completely, then close the valve.
- Drain the water lines. Open all faucets (hot and cold), the outside shower, and low-point drain valves. Run the water pump until water stops.
- Bypass the water heater. Either with a built-in bypass system or by switching the bypass valves to the bypass position. This saves 6 to 10 gallons of antifreeze.
- Add RV antifreeze (the pink stuff, not automotive). RV antifreeze is non-toxic propylene glycol. Automotive antifreeze is toxic ethylene glycol and should never go in plumbing. Most RVs need 2 to 4 gallons. Pump it through with the water pump or a hand pump at the city water inlet until pink fluid runs from every faucet, the toilet, and outside outlets.
- Pour antifreeze into drain traps and the toilet bowl to protect seals.
- Disconnect or remove the battery. Cold drains batteries. Either pull it and store in a warm place, or leave it connected to a maintenance charger.
- Add fuel stabilizer to the gas tank if you’re storing for more than 30 days. Fill the tank to reduce condensation.
- Cover the RV with a breathable RV cover. Not a tarp. Tarps trap moisture and grow mold underneath.
- Set rodent deterrents (mothballs, traps, or peppermint sachets) inside before locking up.
If you’re not comfortable doing the antifreeze steps yourself, RV dealers in WNY (Camping World Hamburg, Camping World Akron) charge $150 to $300 for a full winterization. Time it before the first hard freeze, typically late October on Grand Island.
Off-Season vs Year-Round RV Storage
Most WNY RV owners need storage from late October through early April. Camping season runs roughly April 10 through October 25 at HTR Niagara, with similar windows at KOA Grand Island and other local campgrounds. That’s about six months of active use, six months stored. WNY RV storage and snowmobile storage follow opposite seasonal calendars, which works in everyone’s favor.
Jeff’s Attic Grand Island runs month-to-month with no long-term contract. You can store six months and pull out for camping season, or store year-round if you don’t have driveway space at home. Many WNY RV owners go year-round when their HOA prohibits parking RVs at the residence (common in Buffalo suburbs and Grand Island townhouse developments).
The 30-day reservation hold lets you lock in a unit before you need to drop the RV off, useful when the first freeze comes earlier than expected.
How to Reserve RV Storage on Grand Island
Reserving online takes about five minutes. Your size, price, and any current promotion are held for 30 days with no upfront payment.
- Pick your size from the table above. Match your RV’s exterior length plus 2 feet of clearance.
- Reserve online or call. For Class A motorhomes, fifth wheels over 30 feet, or anything you’re unsure about fitting, call (716) 773-2000 first to confirm availability.
- Bring military ID at move-in if applicable. Active duty, reservists, retirees, and veterans get a 10% discount stacked on top of any current promotion. CAC, Reserve ID, retiree ID, VA ID, or DD-214 all work.
- Drop off on your schedule. All Jeff’s Attic locations have 24/7 access. No appointment needed.
Frequently Asked Questions
Can I store any size RV at Jeff’s Attic Grand Island?
No. Indoor self-storage units have door heights of 8 to 10 feet, which means most Class A motorhomes (13 to 14 feet tall) and large fifth wheels (over 30 feet) won’t fit. Class B campervans, Class C motorhomes under 28 feet, travel trailers under 30 feet, pop-ups, and smaller fifth wheels fit indoors. Call (716) 773-2000 for outdoor or oversized options.
How much does RV storage on Grand Island cost?
At Jeff’s Attic Grand Island, RV storage starts at $75 per month for the smallest unit and runs up to $400 per month for the largest indoor unit.

When should I winterize my RV before storage in WNY?
Before the first hard freeze, typically late October on Grand Island. RV water lines begin to freeze when temperatures drop below 30°F for more than 30 minutes. Drain water tanks, bypass the water heater, add RV antifreeze (the pink non-toxic kind, not automotive antifreeze), and protect drain traps. The full process takes about an hour.
Is Jeff’s Attic Grand Island open 24/7?
Yes. All three Jeff’s Attic locations (Grand Island, Niagara Falls, Wheatfield) have 24/7 access with no appointments. Drop off or pick up your RV on your own schedule.
