First Time RV owner...need some advice please!

We bought ours about two months ago and have a similar story. Despite the checks, orientation, records, good vibe about the sellers, etc. We ran into issues that surprised them when we called (yes they were gracious post sale too)- tires, brakes, minor repairs. Plan on buying a house and a car, and set time and funds aside accordingly. It's all part of the experience- even buying new has plenty of issues that you'll see in these forums. Welcome, and enjoy!
