I've bought (4) new motorhomes in past 20 years. A few things I've learned (some the hard way)
1. Research the unit you are interested in. Find out what problems have been seen. Forums are a great help.
2. A unit may be fine when it leaves the factory, but problems will appear as it bounces down the road to the dealer. Expect post delivery issues.
3. Insist on a complete PDI/Walkthrough before you drive it off the lot - once you do, it's yours.
4. RV sales have seasonal peaks. Don't buy in March/April/May and act like you're the only customer they have.
5. These coaches are an assembly of parts from various suppliers. Much of what goes wrong reflects back on those suppliers, who are responsible for their various warranties.
6. Don't expect dealers who carry a dozen different brands to stock a full line of parts for each brand.
7. When you find a problem, call your service manager and make an appointment to bring it in - saves a lot of anguish waiting. Meanwhile, use the coach and enjoy.
8. Make FRIENDS with service people - they are your lifeline. I keep a glove box full of $20 gift coupons for various restaurants and hand them out for a job well done. Believe me, they'll remember you next time you're in. Works better than a cash tip!
9. Your attitude toward them will determine their attitude toward you. I've been in shops where an angry customer is giving a tech a hard time, and get's a response like "we'll get to it when we can," then turn to me and in the next breath say "when do you want it back, Mr. T"?
10. Don't go in with an "intermittent" problem and expect the tech to be able to find it. Sometimes they can, but more often not, and it'll need to get worse before they'll find it.
11. Like #3 above, if you've had service work done, insist on a test drive before you take it back.
12. Have fun!
