Take your time making a decision. I know full-timing is exciting. I know you’re eager to get started. I know you wanted to be gone yesterday. In these circumstances it can be tempting to buy the first RV you find nearby in your price range just to have that step over with and be closer to your goal, but that’s not the best way.
If you buy the first one you can afford without researching all the options, you may discover that it doesn’t meet your needs well. Take trips to dealerships or RV shows and tour as many different sizes, types, and floor plans as you can. Imagine yourself living in them. Will all your stuff fit? Is the bed long enough, the shower tall enough? Give it plenty of thought.
Once you have found your ideal RV, don’t just assume the current owner or salesperson is being honest about its condition (this goes for new RVs as well as old). Do your own thorough check of all the systems and make sure everything works as advertised. Inspect the RV for leaks and damage. Be nosy, ask questions, and ask to see maintenance records if it’s used. Think about bringing a friend along who is mechanically inclined to inspect it with you if you have no experience yourself, or you can even hire a third party RV tech to go over it for you. It might mean more work now, but it’ll pay off later with an RV that lasts.
Don’t let a salesperson (or previous owner) talk you into a purchase you’re not sure of, and don’t make a purchase decision in a heightened emotional state. Let the idea simmer overnight, and if you still feel like it’s the right decision a day later, then make the purchase.
I’ve heard of so many people who jumped the gun on buying an RV and then it turned out to be a lemon, or they lost money trading it in shortly after for something different because they couldn’t stand some aspect of it. You won’t regret taking the time to make an informed decision.
