Topeka.....welcome to the forum! Most of us, I think I'm safe on this, own the "old" Hi-Lo travel trailers. But, I can give you a rough estimate based on the new Hi-Lo website which shows that their new models have an exterior width of 7'11" and an interior height of 6'2". With the 6'2" interior height, you'll have a height (when the trailer is in the lowered position) of close to 4'. Add on an a/c, too. So, my rough estimate would be a front surface area of somewhere in the 32-36 sq ft. This is just my guess, but I suspect it's close.
