Welcome and great to have you. We bought out 29.4 about a year and half ago but last year was out first year out. Yes, starting out the first year you seem like you are forever buying things, things and more things. Here's my top 10 things I learned (or bought) the first year..
1. Turn the propane knob on all the way not just a quarter turn (and don't run out of propane (don't ask me how I know this...lol)
2. Be patient with the leveling system
3. There's a brand of storage boxes that fits perfectly (Target carries them) you can stack them 2 high to maximize that space over the couch area
4. Replace the stock TV's they are pretty much crap
5. Get a made for RV GPS (if you don't have one already...very important).
6. Don't be in a rush when setting up and breaking down camp
7. Label makers are worth the money
8. A good RV mechanic is worth his weight in Gold...so is your tire guy
9. Valve extensions will leak (see number 8)
10. Control your frustration It'll ruin the whole experience. Expect small issues and go with it.
11 (bonus) start a hard cover RV reference book and write stuff down as you learn it Take it with you on trips
12 (double bonus) The Onan generator can (and will) flip it's breaker under severe load. Find out where the breaker is before you need it (youtube is your best friend)
13 (triple bonus) Coach batteries don't last forever. Ours lasted about 3 years results may vary...
14. There is a brand of those plastic storage drawer towers in Target that will fit in your clothing closet perfectly. Perfect for socks, undergarments, hats, etc etc etc, maximizes space
