What width of car-hauler trailer, and how long is a K-5? The father in law's buying a carhauler and we want to be able to put my K5 and his VW manx on it. Seems like with a 5500 lb K5 and with maybe a 1200 lb VW, 2 3500 lb axles will be pushing it. Is it worth it to get 5000 lb axles? Brakes on just one axle ok too?
