I have a 48' (in reality it's 48' 10") gooseneck for a 68 Firebird and 71 Camaro. Has 40' of floor space. Have a bbq grill, the 68, gas cans, sparetire, the 71, 2 bicycles, generator and fold up table all in that order stuffed into it. The bed in in the attic. Man I need to get a new mattress, that one wore me out over the weekend. :shock:
