Newbee question for long timeRVer's

I bought my class A DP MH brand new just before retirement, in preparation to go fulltiming at retirement. Its now 10 yrs old and I plan to keep it another 10 yrs. But I do all my own maint and knowing the condition of all the major components is a big part of using a 10+ aged vehicle. I would never buy a 10 yr old MH unless it was from a close friend - family member who I knew took as good care as I would. I agree completely with buying a well maintained used MH, but I would look more to 5 yr old units to avoid buying someone elses problems. It also depends on how mechanically inclined you are. Having to take a 10+ yr old unit into a $100/hr mechanic everytime you think somethings wrong, can add up quickly. At 5 yrs old, even a rig that didn't get top notch care is not too far gone to recover. But after 10 yrs of neglect, major problems are almost guaranteed.
just my opinion, others will vary
