Based on the BASS elite circuit I thought Toyota Tundra's were the number 1 choice for pulling a bass boat. I have a Dodge Ram 3500, deisel and get 15.5 mpg towing a 20 ft Xpress. I would have a smaller truck, except I also pull a 38 ft 5th wheel. I retired from Exxon and when the govt. required lower sulphur in the deisel, they spent hundreds of millions putting in sulphur stripping equipment. If you remember deisel was the cheapest fuel before that. If I could, I would have a 1/2 ton gas burning vehicle to pull my boat. In the long run, since most of the time you are not towing, this would be most economical.As far as fuel filters, I've only changed 2 in 75,000 miles. No big deal. Oil changes cost 2.5 times as much, but can also be done less frequently. I do mine at 5000 miles. I also like the Hyundai looks. And agree the jeeps are great vehicles, but I suggest a Dodge Ram 1500 Crew cab with a HEMI.
