G'Morning, MargaretB....we're in the same place you are. We have an '03 F-150 crew cab, 5.4, 3.55 and our payload is 1840....I went and looked at the sticker....again. We are rated to tow 8000#. Our Rocky has a GVWR of 6629#. There will always be someone who says you should just go ahead and buy a 350/3500 because you'll be better off. Where? Certainly not at the bank. Your choice of TTs is one of the lighter ones and you don't need it for that. You're not hauling a mountain of "stuff"....did you ever go and invest in that coffee maker??? You're an AARP member with some longevity, so the chances of you moving to a 35' TT or 5er are pretty darned slim. You just want a truck that's sufficient to tow your TT safely and serve as a daily driver. Is that right?
There is good advice on the forum, but there are those who apparently have very deep pockets and believe that bigger is better. But not all of us. Suggestion is that when you are looking at a truck that may serve your needs, ask the salesman to pull up that truck by VIN#. There is a website by year that you can also check specs, but ask for the actual printout from the factory when the truck was built - they can have it almost instantly. That should match the stickers on the jambs. While we were on our last FL trip, we got to talking weight, etc and pulled into a scale. I called our Ford dealer and they had the complete info for us in less than a minute. The manual leaves some to be desired as far as details. You need the actual from that vehicle. Same rule applies to auto salesmen as to RV.....don't take their word for it, triple check it yourself.
So after you buy the coffee maker and head for the car lots, don't let this make you crazy, which it can. Take it one step at a time, just like with the TT. It's hard to believe that there aren't some nice, fairly new trucks out there that will fit your needs. BTW, if you find a dealer that you're comfortable with, they can check a wide area to see what dealers have what for sale and they often swap around. When I bought my car, the color I wanted wasn't at the dealer I love but they found it in just a few minutes and sent a driver to pick it up for me. You should still be able to work with the dealer you're comfortable with. You might find it that way. Good luck.
