Valet makes a big rig easy
A fifth wheel or Class A is a lot to back into a stall every trip. With valet, our team parks it and has it staged when you call ahead. Check roof AC height before choosing indoor. At Norwalk and Altamonte Springs: At 13′ 4″ tall it won't clear the 14′ indoor door: we leave 1′ of clearance, so indoor takes rigs up to 13′ tall. Outdoor is the fit here.
