When you inspect the rig, notice WHAT things you would do for maintenance and updates. Then consider the costs in time, money, and effort.
Things like new tires, resealing roof, LEDs, water expansion tank, etc.
We bought low and had to do the work ourselves. We could have bought one that had all the maintenance up to date, but we were going to change things anyways, so we bought right.
Either way is acceptable ;)
Also consider the DISTANCE. How much will it cost in time and money to travel to it and bring it home? If it isn't what you want, that will be wasted.
IMHO, condition is king- especially with RVs.
