The trailer has to be level when towing. There’s no equalizer system as in a camper trailer. If you have a flat tire you won’t know it since the other tire on that side will support the weight on its own. Likewise if you hit a pothole with one tire the other tire supports the weight and neither tire will go into the hole unless the hole is bigger that 3 ft. Just contact Ben at Hoosier trailers and he’ll build you what you need (260) 463-3513
