We just traded our second tent trailer in on a travel trailer,after 18years of them. My wife and I were shocked at just how much stuff we had in it. Use the floor,you can fill that up to the slides. We never used totes, wastes space. Our first one was Bonair 700,a 7' box.Two boys and a Lab.Into the Cherokee we put the main cooler and the clothes duffle bags. Bag everything,dust was the biggest problem.A lot of people pull the water tank and use that space.
Same here, 20 years in a PUP and now a new TT. Now we have to much space!
