"mchero"......If you want super singles, buy them! You've spent this entire thread chewing out people who didn't agree with your attempt to justify the purchase of them in your mind.
If they were all that great, there would be more than just a few RV's using them. Even worse is the attempt by the ONE owner to justify why he wasted his money. He would have been the smartest guy around if they had become popular and he got his at a low price, before they went up, but they didn't become popular.
There is ABSOLUTELY no value running them on an RV.....a point that is pretty hard to argue, but I'm sure some will try, at least two on here!
