I've a 2010 Montana as well, but it's never had anything by Rieco on it. The original front leveling jacks were Lippert, but I've replaced them with two motor Bulldog ones. As for your tires, were they the original ones? If so, they were way overdue for replacement, especially if they were Marathons. My wheels were made by Tredit, and, yes, that model isn't made any more. Tredit only makes ones with more standard valve stems vs. the old inside mount ones. Tredit does make wheels that will fit correctly though. You could get by with only replacing two on one side vs. all four.
