Sorry to hear of your trials with your RT. Except for some drama over the drive shaft induced by a poor repair ours was relatively trouble free, with regular maintenance. I hear you on the two fan clutches, the Hayden that I put on lasted just over a year. The Oreilly brand was still good at the sale.
We bought it with 122k on it and sold it in 36 hours with 222k on it.
We did have the awning fall off at the USFS site north of Mammoth Lakes and the coach A/C went kaput after placing the for sale ad. I knocked a grand off the price and the buyer was good with that.
I still think the video that you did for replacing the A/C was most excellent, thank you for that.
We've replaced the Road
trek with a 23 year old Safari
Trek. Lotsa fun "making it ours".
