If that unit had been advertised last spring when we were looking, I would have probably gone to look at it! If it is mechanically in really good shape, you may have to consider a few things. The carpeting may not look as good as it does in the pics....had that happen with a 2008 HR gasser that we went to look at. And, in those years, that can be a lot of carpet to replace which can be pretty pricey if you can't do it yourself. You may find that it's time for a sofa upgrades, but that isn't a problem as long as you plan for it financially. I'd be surprised if it doesn't need a set of tires and possibly a brake job. If so, you can save some bucks by going with Toyo or other tires that aren't as expensive as Goodyears or Michelins. Also, you may want to replace the mattress. But if the price is right and you have some money in the budget for upgrades, it could be a good way to hit the road.
One more point....make sure it has two AC units. In a motorhome that size, you really need two AC units if you are going to be in hot summer weather. Also, find out the size of the generator. I suggest making sure that it has enough capacity to run both AC units at the same time or at least a power management system to effectively alternate between the two. Another cost may be replacing the coach battery and/or the house batteries. I don't mean to sound negative, but when looking at a used motorhome, there's a lot of stuff that does wear out and you don't want to purchase one without being prepared for some expenses.
If you don't want to worry about expensive repairs, you could look at getting an extended warranty, but they are pricey and many would argue that you're better off to take the cost of one and just put that money aside and save it as a repair fund.
Good luck in your search.
