I just bought a new to me 32' 5er. I'm in the process of getting a new ram 3500 diesel 4 wheel drive. I plan to tow doubles with my flatbed with my toys on it. I've seen this done many times at dumont and have read about this alot. A few people on some forums have said not to do it because the frame of the camper won't support the weight of the second trailer and till pull floor away from the walls. Anyone have experience with this or do I just need to build a new subframe to put the hitch on?
