I tow a two horse trailer with a F250 5.4 liter with 160K trouble free miles. I looked at getting a diesel which would have cost about 10K more because even though it was only 6K more for the engine I couldn’t get one without other upgrades. I just have a plain old interior so the wet dogs can hop right in and I can hose her out. The only reason to buy a diesel is if you have a heavy load to haul. How heavy you contemplating? If I had a real big trailer like a 4 horse RV (wish wish) I’d go with a Ford F450 diesel. I like a lot of truck in front of my trailers so the trailer knows who’s boss. Diesels last but the maintenance is a lot higher. Brand is really a hard call since there are better combinations than others in all brands. I am a Ford guy, on my 5th Ford truck. Have Toyoto trucks for light hauling, good ride. Silverado seems most stylish and car like ride to me, other than Tundra. I had one Chrysler in my life, with the slant six, and that was a nice car, but I traded it for a 72 F250. Bottom line, what’s the load you gotta haul? Also nice toi have a dealer close to home.
Goosneck trailer. Nuff said.
