We sold our popup camper and have been looking at the travel trailers. There's a lot to choose and the one that I like is GVWR'd at 7300 lbs. I'm wondering if I'd be pushing my luck, granted the dry weight is around 5300 lbs so I guess as long as we don't pack too much stuff we would be w/in spec. But it occurred to me that maybe I could tow a little more with some mods. Is that true?
