Buying Strategy (looking for opinions)

For me, #2 would be a no brainer. Once you go used, then condition is more important than the year so a well cared for 2010 could be just as good as a 2016 or 2018. We bought a 2003 30 ft. Itasca Class C in 2012 with 21000 miles for $23000 cash and have had no regrets even though it is just a 4-speed trans. Now has 58000 miles. Yes, we've spent a lot repairing, replacing and upgrading but no where near the 80000 plus it cost new. RVing just is expensive one way or another. If you can pay cash, that's a huge factor as you will avoid interest and have those monthly payments free for investing or whatever. Two big MH advantages you didn't mention- on board generator with electricity at the touch of a button and much easier backing into a site.
