I agree with the other posters about the weight. I wouldn't want to try and tow my bunkhouse with any less truck than I have now. My next truck will probably be a MDT, as the wife is already looking to replace the trailer with a bigger bunkhouse model.
. Also, since you're from Calif. keep in mind that a lot of the state park campgrounds have a '32 max length. At least one of them near me has a '32 foot box painted on the ground at the entrance they use to check length.
Haven't been to Yellowstone yet, though it is on the list. Good info to have about the overall length. I'm in area of '55 feet overall length. My trailer is '37 bumper to hitch, and our trucks are going to be close in length, so that should give you some idea of how long yours would be.
