What kind of towing vehicle should I get for a 26ft bnkhs

I'm in the camp that a little more than you need is great. I have a 2500 Diesel and pull a 6200 pound(loaded)trailer. It is super easy towing, never a power problem. And if the bride and I decide we need swivel rockers and a larger trailer to go along with the swivel rockers we are all set. I would say the disadvantage to having a new Diesel is the constant maintenance that is needed to maintain warranty and annoying warning lights on the dash. But the power and tow mileage are pretty much unmatched(just my opinion)
