Enclosed Trailers....

[PxTx]

I agree, the 6.0 would be fine and the 5.3 would be the minimum I would want. I did have a friend tow a 20' for 2 years with the 4.8 but he always talking about stepping up to a 6.0 which he did with an Escalade.

Although the 5.3 and a 20' is the minimum, I would say you stand a good chance of finding more for the same money spent if you are looking used.

I was looking for a 24' trailer when I found my 28' (locally but on ebay!). I now bring a golf cart and a scooter as well as all of the tools and a generator with me.

I'll bang the 8100 drum one more time in your case. It seems the 6.0 isn't really that great on fuel. Basically about 1 mpg better than the 8.1. The up side of the 8.1 truck is you get the Allison trans which will spoil you. With the price of fuel, people are afraid of big motors and you stand a good chance of getting a better price on an 8.1 than a 6.0 so for no real more money, you'll have something that is above the minimum and better suited for the task.
