Haven't checked on the availability of Monaco/ R-Vision motorized parts, since they shut down completely in this area a few years ago and moved everything to the west coast. Then in the last year Navistar has moved everything back. I have plenty of generic parts available from the RV surplus stores in the area, however the pricing has gone up a bit after the big shake out of the past 4 years. The only things I have to do yet this fall that I know of, is change the water fills, which the gravity fill shows a bit of aging and the pressure fill is very loose and hard to tighten enough without pliers to keep from leaking even with new washers. We plan to add a sealed AGM battery in a battery box under the couch and replace the underfloor battery even though changed out as a condition of sale, to another AGM before our trip. next year.
