Abstract: Air conditioning conversion kits ideally adapted to be retrofitted to vans, trailers, campers, or other recreational vehicles providing improved air conditioning efficiency and flexibility for campers. The kits are esthetically harmonious with the existing vehicle, both on the outside of the vehicle and on the inside. Our preferred systems enable use of the A.C. outlet at a campground or trailer park for air conditioning the vehicle while stopped, without running the engine or draining the battery. Bulk is reduced by physically separating the condenser from the evaporator. The preferred "Continental kit" version incorporates major structural air conditioning components within an attractive spare tire carrier disposed on the vehicle rear. The vented circular carrier attractively houses the condenser and the compressor, along with related accessories. The evaporator portion of the system is incorporated into the vehicle's interior door panel.
