Will My RV Fit in a 14x35 Storage Unit?

Glenwood Springs Storage • November 12, 2026

A 14x35 enclosed garage is the biggest unit we rent at Glenwood Springs Storage, and it is the one people ask about most. It is fourteen feet wide and thirty-five feet deep, with a roll-up door, four walls and a roof. That is room for most travel trailers, toy haulers and Class C motorhomes, but "most" is not "yours". Here is how to know for sure before you rent.

1. Measure the whole length, not the length on the brochure

RV makers quote a "floor plan length" or "box length" that leaves out the tongue, the hitch, the spare tire and the rear ladder or bike rack. The number that matters for a garage is bumper to hitch: the rear-most point of the rig to the front tip of the coupler, with the slides in.

A trailer sold as 27 feet is often 30 to 31 feet bumper to hitch. Add about a foot so you can close the door without touching the back of the rig, and you have the length you actually need. Our 14x35 garages take rigs up to about 32 to 34 feet that way.

If you are close, try the Will it fit tool on our RV and boat storage page. It draws your length to scale inside each of our garage sizes.

2. Width: the unit is wide, the door is narrower

Fourteen feet of width is plenty for an 8.5 foot trailer with room to walk around it. The tighter number is the door opening, which is always narrower than the unit. Measure the widest point of the rig, including mirrors, awning arms and any fender flares, and keep a little margin on each side so you are not threading a needle every time you back in.

3. Height is the question to ask us

Roof air conditioners, antennas and solar panels add height. Measure from the ground to the highest point on the roof, then call or text us at (970) 633-3122 with that number before you rent. We will tell you straight whether your rig clears the door.

4. Smaller rigs, boats and trailers

Not every trailer needs the biggest garage. A pop-up camper, a utility trailer or a boat up to about 24 feet bumper to hitch fits a 10x25. Up to about 29 feet fits a 10x30. A side-by-side on its trailer usually fits a 10x20 or 10x25. See our size guide for what fits in every unit.

5. Why enclosed matters here

Winter in the Roaring Fork Valley means snow load on the roof, ice working into seals and months of high-altitude sun on the gelcoat and decals. An enclosed garage keeps the rig dry, out of the sun and out of sight behind a locked door and a keypad gate. Our garages are not heated or climate controlled, so winterize the plumbing as you normally would.

Ready to measure?

Write down three numbers: bumper to hitch, widest point and highest point. With those, we can tell you in one call whether a 14x35 is right. Our 14x35 garages are usually full, so join the waitlist from our unit list and we will contact you the day one opens.
