RV, boat & equipment covers in Sullivan, MO
UV and hail are what kill a camper roof and a gelcoat finish. A tall steel cover keeps the sun off for a fraction of what indoor storage costs over a few years. The trick is getting the height right.
How tall does the cover need to be?
Measure your rig at its highest point — usually the A/C shroud or a boat tower — and add one to two feet of clearance.
| What you're covering | Typical height | Cover height |
|---|---|---|
| Pop-up or small travel trailer | up to 10 ft | 12 ft |
| Travel trailer with A/C | 10–11 ft | 12–13 ft |
| Fifth wheel | 12–13 ft | 13–14 ft |
| Class A motorhome | 12–13.5 ft | 14–15 ft |
| Boat on a trailer with a tower | 8–10 ft | 12 ft |
Cover heights are the leg (eave) height. The peak of a vertical roof sits about 1–2 ft higher than the leg.
How long and how wide?
Length
Take the length of the rig and add at least 5 ft so you can hitch, unhitch, and close a rear panel without backing into it. A 32 ft motorhome wants a 38 to 40 ft cover.
Width
12 ft covers a single rig with slides in. Go to 18 or 20 ft if you want to walk both sides, open an awning, or park a truck alongside. 24 ft fits an RV and a boat side by side.
Open, part-enclosed, or fully enclosed
Open cover
Roof and posts. The cheapest way to stop UV and hail. Add gable ends to keep driving rain off the front and back.
Partly enclosed
Close in the two long sides and leave the ends open to drive through. Good wind protection without a door to deal with.
Fully enclosed RV garage
All four sides plus a 12 to 14 ft roll-up door. Lockable, and it doubles as shop and storage space in the off-season.
Boat & pontoon covers
A 12 ft wide, 24 to 30 ft long cover at 10 to 12 ft tall handles most runabouts and pontoons on a trailer. If your boat has a hardtop or a wakeboard tower, measure to the very top and size the height from there. Closing in the north and west sides blocks the worst of the weathering.

Anchoring and wind
A tall cover is a big sail, so anchoring matters more here than on a low carport. We bolt to a slab with wedge anchors or to the ground with long mobile-home anchors, and we recommend the 12-gauge certified package for anything 14 ft or taller. If your site is open and wind-exposed, tell us — we'll add bracing.
Anchors only hold as well as what they're in, which is why the pad matters on a tall cover. If the spot is soft, sloped, or holds water, our crew grades it and builds a compacted gravel pad or pours a slab before the cover goes up. See site prep & groundwork.
Questions we get a lot
Can I add sides to an open cover later?
Yes. Panels bolt to the existing frame, so you can start open and close it in a side at a time as the budget allows.
Do I need concrete?
No. Level ground or a compacted gravel pad works for an open or part-enclosed cover, and we can build that pad for you. A slab is worth it for a fully enclosed RV garage — see pads, piers & footings.
Will it fit my Class A?
Measure to the top of the air conditioner and give us that number. We size the leg height so the roof bows clear it with room to spare.
Is rent-to-own available?
Yes, on covers and enclosed RV garages both. See financing and rent-to-own.
