Don't be offended but you've only shown the superficial stuff. Start at the top of the vehicle and closely examine it. Check out all of your systems to insure they work. Fire up the stove, oven, furnace, hot water heater, fridge, AC. Examine the tires for their age, not how good they look. Ask to see service records. If they can't provide them ask if you can get the previous owners phone #.
Whether you are experienced or a 1st timer you really need to look the unit over. For most this is a very large purchase. Don't get excited because it looks pretty. You're gonna be living in it and driving it. Check out the internet to see what a comparable unit is selling for and adjust your price accordingly ... unless you know for sure you have a gem.
If you are new to motor homes find someone who has some knowledge about them. You'd be amazed at what first time buyers miss.
If you have friends who make you laugh, spend lots of time with them.
