Thank you all SO much for your help. There is so much to learn! Now I have another question and maybe I need to ask it on a different thread, but...we found a 2012 F250, 6.7L Power Stroke 4V Diesel V8, 3.55 electronic axle, FX4. It has been lifted, I'm not sure how many inches but I can get in by stepping on the sidestep. Is this a good thing or a bad thing for a FW or TT?
The crew cab tows 14,000 lbs in the F250 or F350, and 16,000 for a Fifth Wheel. In the specs it says payload is 3,290 lbs. We definitely do not want to go up to a Dually.
