I bet I'm not alone in my horror at reading in this forum people asking if they can tow heavy caravans with little cars. Surely on the layout section of this website there should be the rough rule of thumb . Max tow Family car = 2 berth or light 4 berth. Heavy car = 4 berth. 4wd = twin axle. I partly blame the manufacturers I have owned 3 of the same Swift model, 4 berth rear bathroom that has gone from 1994/1150 KG to 2002/1300 KG to 2004/1435 KG. The manufacturers don't seem to be making quality large light weights . The Bailey front bunks are too short. The lunar gas locker floor, I've seen stronger plastic bags. Your thoughts?
