If it is well cared for, good mechanical and rv systems condition and un-molested (i.e., not full of hack repairs), it should be a very serviceable unit. And a great value at that.
Again, the miles are super low and that is a bonus, but don't falsely believe that the chassis and drivetrain will be totally relaible as if it was 3 years old and driven 15k a year.
i would have no issue with it, but my view is that I can/will repair most anything save for rebuilding the engine or trans as it comes up.
Realize even "simple" repairs are expensive if you're paying someone or a tow bill.
Are you comfortable with major pre emptive maint/repairs before you embark, or potentially fixing cooling system or brakes or ..... For example? Or is it a tow truck to the nearest shop and a repair bill for you?
At a minimum, all fluids, hoses, belts, tune up, newer tires etc "should" be done to minimize the chance of the "little" stuff breaking down. Budget for that.
Not trying to be pessimistic but that's what you need to prepare for with an old rig. It's not a certainty, but you dunno until it happens.
The RV portion on the other hand is less of a concern, IMO. Most repairs are fairly basic. And aside from losing the fridge, for example, can be worked around with relative ease. (You can figure it out for a few days if say the water pump dies or heater don't work, unlike breaking a fan belt on the rig and being out of commission on the side of the road without the knowledge or parts to fix)
IMO, the nicest 23 year old class C out there is worth maybe $10k tops, budgeting for making it reliable.
I know this sounds negative, but it's how I'd view it having good knowledge of mechanics, and kind of a prepare for the worst and then you won't be disappointed and likely have a better experience.
