Several reasonable recommendations. Based on your statements and goals, weight of existing trailer, daily driver comfort, (and especially if I loved my red Explorer...). I'd head over to Whitesboro and take a drive in this:
F-250 Lariat 6.2LF-250, 6.2L Gas engine, Lariat Ultimate Package, moonroof, Quad beam headlight package, Blind Spot Information System,(great for trailer towing), 10,000LB GVWR, nearly 3,500LB payload, and great road manners, Did I mention it's red?:C
Window StickerI think these have been a best kept secret in towing, since folks so often run out of payload, and don't always want or need the diesel for every application. There's a good discussion on the F-250 Lariat on that "other" RV forum,
Towing with the 6.2L truckI had no idea, these trucks were so well equipped today, I'm basically a Ram 2500 fan, (in the category of most features for the lowest price), but I'm telling you Ford has it going on with this gasser version. It is the answer to all questions "will my 1/2 ton tow this?" without having to get the one ton dually diesel.
Quad Beam headlight packageBlind Spot Information SystemEdit: for the budget-conscious, here's a nicely equipped F-250 XLT 6.2L priced a fair amount under an F-150 Lariat 3.5L Ecoboost Supercrew: (Fairfield, TX) Don't misunderstand, I love the Ecoboost engine, but just use the right tool for the job at hand.
