How do I choose the right wall height and door height for my RV or boat trailer (including rooftop accessories)?
Measure your rig from ground to the tallest rooftop item, add at least 12 inches for clearance, then pick a door that size (14 ft works for most 13 ft 6 in motorhomes or T-top boats). Order your TruSteel RV and boat storage steel building with an eave height 2 ft higher than the door so roll-up hardware clears.
Start with the real height of what you are storing. Park the RV or boat trailer on level ground, raise antennas, racks, or T-tops, and measure from pavement to the highest point. Typical heights run 9-10 ft for Class B vans, 11-12 ft for fifth-wheels and T-top boats, and up to the legal road max of 13 ft 6 in for Class A coaches with rooftop A/C. Door clearance.
Add a safety buffer of 12–18 in so you are not backing in on the bump stops or worrying about a future satellite dish. That means a 12-ft rig calls for a 14-ft roll-up or sectional door; a 13-ft 6-in coach needs a 14- or 16-ft door. TruSteel supplies standard 12×12, 12×14, or 14×14 roll up doors or can engineer most custom openings. Wall (eave) height.
Overhead doors require roughly two additional feet above the door for the coil and track, plus space for insulation and lighting. Match a 14-ft door with a 16-ft eave or a 16-ft door with an 18-ft eave. Going one size taller now is cheaper than raising a frame later. Future-proofing. If you might add roof solar, cargo boxes, or a bigger boat, size up the door, not the width.
