About to Buy a Used Class C, Looking for Advice

As midnightsadie noted, YOU need to check the date codes on the tires. No matter how "good" they look or how good the tread appears, RV tires need to be replaced at about 6 years old. Also, as noted, carefully check for water leaks, especially in the over cab bunk area. Sniff around and see if anything smells moldy. I would also get on the roof and look at it's general condition and especially to look for cracks. Best wishes on your purchase.
