Hi guys: I bought my Bigfoot 17' new in 1993 and still have it. Been a great trailer. First year we had it I put a 15 K Dometic A/C unit on the roof. Just replaced it with the newer version of the same a/c unit. Replaced the vinyl floor with engineered mahogany wood, the h.w unit, and fridge
. Appliances wear out, but, the body of the trailer and the frame is very durable and still look like new. Good wax X2 per year and covered in the off season keeps them as good as new. Weak roof? As previously stated: some early models, but I never thought about how I walked or worked on the roof of the Bigfoot.
