If you log into this site with your phone you should have no trouble posting pictures. Your phone can also download the pictures into your computer. Sounds like a better than average Toyota motorhome. I think you should ask 18,000 for it. Unfortunately, it's getting late in the year. They sell better in the spring.
I would try posting it here
Toyota Motorhome For Sale: Chinook, Dolphin, Sunrader, Craigslist Used (toyotarvforsale.com)
or look for a facebook motorhome site. Ebay is a possible option too.
Don't leave out all the improvements and upgrades. Lots of people are looking for something they don't have to do a bunch too
