Welcome! My wife, daughter and I camped in our pop-up for a wonderful year (Coleman Niagara) before making the huge step up to our fifth wheel!
Pretty crazy, but exciting!
Before you commit to the F-250, might I suggest that you run the numbers and ensure that the truck can handle you, passengers, your stuff and the pin weight while still being within the truck's ratings? It very well may be- but you're in the perfect position now to verify before you've signed on the line.
