For all the full timers out there I saw this and thought it was kinda neat. I really don't have the need for this, but if I were full timing I might consider it. http://www.pplmotorhomes.com/parts/rv-p ... washer.htm
This site is pretty good with other things we might need and their prices are competitive.
I think that space is even more precious to full timers and this thing takes some up. Also, full timers tend to be no more than 2 people and, imo, a dishwasher for two people is unneccesary.
