Actually the TRX is a class C. There are only four class official designations of RV's, so says RIVA, manufactures official documentations, most in the know insurance co's, and a lot of state RMV's.
Class A -Built on a stripped down heavy duty truck or purpose built chassis, no cab. Entire body manufactured by RV company.
Class C -Built on either a cutaway or chassis cab truck frame..cab already on. Body with or without cab over manufactured by RV company.
Class B -Built on road worthy completed vans. Interiors and some exterior modifications completed by RV manufacturers
Towables -Anything that has to be towed by a vehicle.
But I guess we can call them what we want
