Class A motorhomes and large fifth-wheel trailers present two simultaneous dimensional challenges that this building is specifically sized to resolve. Roof heights on full-profile Class A coaches reach 13 feet 6 inches at the rooftop AC units – requiring a door opening of at least 14 feet clear height and an eave that carries the structural header load above that opening without deflection. Length on production fifth-wheels and toy haulers reaches 43 to 45 feet including the hitch overhang, requiring a building depth that keeps the rear of the vehicle inside the structure with the entry door closed. The 80-foot depth and 16-foot eave address both constraints simultaneously without dimensional compromise on either axis.

The 40-foot clear span produces approximately 18 feet of usable width per vehicle bay after accounting for wall thickness and a 4-foot center clearance buffer between the two stored vehicles. That buffer width allows slideout extensions on both vehicles to deploy simultaneously – a practical necessity for owners performing interior maintenance, loading, or inspection without moving either vehicle out of the building.

Overhead door configuration on this building type requires deliberate planning. Two independent 14-foot-wide by 14-foot-tall doors on the front elevation allow each vehicle to enter and exit without disturbing the adjacent bay – an operational advantage over a single wide door that forces sequential entry and exit when both vehicles are stored simultaneously. Electrical provisions for shore power connections, battery maintenance charging systems, and interior lighting should be specified per bay rather than as shared building infrastructure.
