Don’t know anything

Agree that you should study floorplans rabidly and then choose the TT first. Only then should you start thinking about your tow vehicle. If you cant tow from the lot home, just ask the seller to do so. I've not met a dealer or individual that wouldn't do that locally. If its long distance, there are folks you can hire professionally.

You do know you still need a domicile state to register your vehicles and get your drivers license and be able to vote. What are your plans to handle your mail?
There are things to think about not just sell everything and travel around the country.

Your title is a little frightening. What is your goal? Are you trying to live cheap or do you want to travel around the country or something else? Are you some tech worker who will need fast, reliable Internet to work on the road? Are you aware that if you park an RV in a cold or hot climate you will spend a lot of money to heat or cool it? And RV parks by the night can be more expensive than you might expect.

I strongly recommend a used one first. For starters, there’s no guarantee that you will even like the experience. Second, the floor plan that you first thought would be perfect or at least sufficient may turn out to be something you really don’t like.
Will you be doing any off grid camping? If so, look for the biggest holding tanks available.
Going to the shows is a good idea. If you find something you like leave your contact info with the salesman in case he gets a good trade in. Do some online shopping to get an idea of what you may like.
Lastly, keep me in mind, I love rv shopping and I get a tat jealous.
Happy shopping!!!!

I’m not sure how much stuff will be with me. The rest will be in a storage unit. I’m fairly mechanical. Is there a resource on the upkeep that needs to be done?

Thanks for everyone’s help!

Here's an article on new vs. used:

Lots of decisions. Unless you can shake out the bugs before you launch (and I strongly recommend that), getting warranty work done is more difficult as a fulltimer because you can't just drop it off at a dealer. There are still mobile RV techs and RV service centers + getting reimbursed, though.

full time is a different animal. how much "stuff" will be living with you. I camp light but for an extended stay would be very heavy. Also how mechanical are you? maintenance will be constant. the problems you mention are more often than not from lack of upkeep not from a brand specific problem.

The questions for the OP start with trailer size, which also then dictates Truck size, and drivetrain.
One person alone even with some dry camping can get by with a 25' box and a half ton truck pretty easily. ie; a F-150 with a tow package and either a 5.0 or 3.5 Ecoboost.
Mid lever trailers for example could be 2520 Passport models or 223rbs Coachmen.

Or you could look for heavier trailers, with longer living spaces, and go to 2500-3500 trucks with or without diesel powertrains.
It's all up to your taste and wallet depth.

Well, I could swing the money, but the money supply is far from endless, so I would like to make smart money decisions. I guess space for four. Just me for sure, but I could see others joining at some point. Full-time. I can see 2-4 weeks in one location before moving on. I have read people writing about some brands with poor manufacturing, leaks and busted floors?
