[QUOTE=avolnek;424439]With the truck you have, I'd have to say the travel trailer is going to be the way to go due to the lack of payload on the truck. Regardless of the pin weight a fifth wheel is going to take up a LOT of air space. Air space means more resistance meaning harder to pull as well as catches a lot more side wind! With the half ton pickup you don't have much weight, nor can the 5er weigh too much but it still takes up a lot of air space... A lot of air space taken up and lightly loaded in a cross wind is a BAD thing!
Another fear I am seeing for you is regardless of what you buy, I feel you will not like the 3.55 gears... Those are a mileage based gear set and tend to be a bit shallow for towing. Not saying they wont do the job as they will and they will do it all day long for you without any trouble! Just be aware that you will have to spin the motor just that much faster to maintain speed. As well as your transmission will probably be shifting more often than not... again, not saying it wont do it nor am I suggesting not to, just wanting to forewarn you...
X2. 1/2 ton trucks are still LIGHT duty trucks. You would need air bags on the rear suspension, along with a tire upgrade. But those 3.55s I think may be the deterring factor.
