Fifth Whl vs Trvl Tralr

I fulltimed in a fiver for a number of years, but had to give it up due to a sudden health crisis. The fiver towed beautifully, and I used a short bed 1 ton diesel, single rear wheels without a problem. There is still some concern with a short bed truck when making a very sharp turning maneuver but there are special hitches that address that possibility. I got by with a standard hitch by just being careful when making tight turns.
A big plus factor with a fiver, as others mentioned, is extra room, not only inside, but for storage as well.
