There are a lot of things to know-
- suitability of your tow vehicle + trailer (if getting a trailer)
- buying the essentials (which are way less than people say)
- buying the “should haves”
- considering memberships to save you money
- finding/making reservations
- learning how to use your new RV
It’s a lot but take each one step by step. As you find specific questions, ask those. I find specific questions get better answers than general ones.
