Hey driver.Relax.Keep asking questions!
Ok, disclaimer.Old mechanic, non Ford lover.Always talk a lot of smak about Ford's.Chevy guy.
But I always end up adding a Ford to my fleet.I just did again, with a late 90s F-150.
Save your $$ on a new one ( read the rusting complaints on the 2021 F-150s
)
Buy a used F-250.Its a bigger tow vehicle.Bigger is always better, for trailer yanking.Especially if new to yanking trailers.
Moving on, save yourself $$$ by buying a used Airstream.Problem now is, it's a sellers market for used RVs.
Let's say a 2005 or whatever.Axles will most likely be ok.These Airstreams have a primitive suspension system.Thats why they look cool + ride low.Like a hard tail Harley chopper, with a primitive suspension system.
.Dont be too scared of a used one.But, again, it's a sellers market.
If you're going to full time it, and want a towing solution, that will give you plenty of additional cargo space a truck wont, buy a E-350 Ford 1 Ton Cargo van.They take a beating, I'll admit, and make storage so much easier, keeping a lot of stuff, like generators, easy to get to.
