ANY I repeat ANY so called 3/4 ton or 250 2500 truck will tow it just fine. A diesel will make it easier but the cost much higher.
Be careful asking this here as there is a cohort of folks that think you need a one ton dually to tow a TAB trailer.
A properly spece'd and set up 1/2 ton will also do it. But here I risk the ire of the "Math" set who may come on with reams of figures to show it is impossible...It's not.
But also keep in mind that it is unlikely, depending on how you use the trailer, that you will reach the full Carrying capacity. I have never gotten close to my CC and I full time.
I weighed everything as I loaded it originally and was WAY WAY within the limits. (and yea this included propane and fresh water.
My general advice though would be to get the biggest truck you can afford with foremost in your mind HOW MUCH YOU WILL TOW and What you plan to do..ie Full time vs two times a year to the lake...
