Not much from the pictures
They have a lot more in it than what they are asking"I think" from looking at pics,shows a couple vents...maybe fridge and heat.
Get more info posted as soon as you look at it,me and others are on here daily,only downsidei can see right off is from bathroom pic,which shows "stock" floor.
Post more pics(if possible...use photobucket dot com ,quick and free.
Find out what engine,trans (probable auto allison) and what appliances iithas and what works...a couple hours"too thiink about it" shouldn't kill the deal.
Price with limited knowledge looks good
Of course this is my .02
