Reason I ask is that the 1R12-431 is a Monaco proprietary part and the specs have been kept private for some reason so it is hard to find a crossover. Thanks MartyRe: Samsung RF18 and inverterThank you all for your replies. They have been very helpful in my decision. MartySamsung RF18 and inverterI know this subject has been discussed many times but I would like the latest information possible. I just installed a Samsung RF18 refrigerator in our motorhome. The coach has a 2500 watt Trace/Xantrex modified sine wave inverter. I know a pure sine wave is best BUT, has anyone had real world experience running this refrigerator from a modified sine wave inverter? I just don't want to buy a $1,500. inverter if I don't have to. Thank you, MartyRe: Allison 3000MH WTEC 3 electronic control system dataMoisheh, where do you get your information? I have been delivering brand new class 8 and 7 trucks from the manufacturers to dealers (mostly fleets) since 1998 and many hundreds of them have had the Allison transmission in them!Re: Fiberglass Roof cleaningI wash mine once or twice a year and wax it the hard way (hands and knees) every two years. Last August I washed it then waxed it (standing up)with Mop & Glow. It has never looked so good. I recommend at least trying it once. I will never go back. MartyRe: samsung 197Considering an Rf 197 refer is kind of a moot point, they are no longer in production. There is another Samsung but it is larger and hopefully they solved that problem. I have the 197 in my 02 Thunder and did the little mod to it and that solved the problem. It is an upgrade that I thought long and hard about and I am glad I went with the residential refer. MartyRe: Tire questionThank you for the replies. MartyRe: Tire questionYES, I need 18 ply tires, that's why it has to be a J rated tire.Tire questionDoes anyone have any tire experience with the Firestone FS561 tire in the 275/70Rx22.5 J rating? Reason I ask is that there are very few that offer that size at that rating and it does have to be a J rated tire. Thanks, MartyRe: Eternabond tape to secure coax on a roofThank you for the replies.
