You have recieved many good suggestions, I will add; when we switched from the PUP to the TT we used the same stuff, we just did not have to pack and unpack it. We added a few more item as the trip progressed.
I did add; a 5 gallon gas can, chocks, hydraulic jack, leveling boards, small air compressor, torque wrench and a spare tire which did not come with the trailer.
My wife and I are pretty minimal but we like the TT for its shear convenience and creature comforts.
I do miss driving through the fast food drive-through and the PUP was a lot easier to maneuver though gas stations. It also got a lot more than 10 mpg.
My TT is only a 26 footer so it handles nice on the road and in the city.
Have fun.
