If occasional RV puller with some commuting, perhaps a gas 1 ton might work best; the gassers are a tad less expensive to maintain and you may not need tons of torque although most modern gassers are adequate. I would look to the future and get a one ton for sure. If you do see a great deal on a 3/4 ton, be sure to check the payload sticker carefully as many, especially the fancier ones don't have much.
