Here is my opinion from both reading hundreds of posts on this forum and my personal experience. Many RV'rs go up in weight from the first trailer up to large toy haulers within their RV'ing time. I had two TT's and a 5th wheel and started with a 1/2 ton truck, suburban, and now a one ton 3500 SRW. So, if you're thinking of a good truck to pull a TT, think one ton 3500 diesel. There is minimal difference in price between the 2500 and the 3500 and diesel will give you the stability and power to tow almost anything safely. I've recently bought a TC and will use the 5th wheel or TC whenever I want. If you can afford it, do it right one time and keep it for any future purchases too.
