Possible New Purchase

I am very close to buying my first rv class A motor home.It is just a 5 hour (hopefully )drive to inspect this baby.Weather long term is calling for snow squalls and white outs.You have to actually drive in this **** to believe it.Pardon my French.

It may be closer to a 10 hour drive.

My Canadian brothers and sisters know all about this.

This unit is a (1999) Damen Challenger,50,000 miles $15,000 and appears from the pics to be in pretty good shape.

I know the basics like checking the oil dipstick for a milky substance indicating water in the oil indicating a possible head gasket problem.

Checking the exhaust when cold starting to see if traces of blue smoke are present to indicate cylinder ring degradation.

I also know to check the corners inside the unit for traces of water leaks.

Is there anything else I should be looking for?

I have to admit I am a bit nervous about all of this.

$15,000 for me is a big purchase.

I am recently retired and on a fixed income.
I cannot afford a major screw up in this purchase.

Is there anything I should be on the lookout for?

Any opinions would be greatly appreciated

I am very new to this!

thank you
