Harry, I've read most of your posts over the last two months and I get mixed messages. You would consider a used Prevost but you are concerned in this post about depreciation??? Over 40' DP's are not a cheap sport BUT they are the nicest way to go down the road and make great boondocking machines BUT most owners do not want less than 50 amp FHU's every night. While I highly recommend getting "educated" It's hard to make the number's work for owning an expensive DP especially if you are on a budget. Some days I do not think you are and others I do???
Some brands have been around longer than others (including bankruptcies) and as such have more clubs that you can belong to. We are currently on a Monaco in Motion caravan in the Canadian Rockies led by a fellow member for VERY LITTLE COMPENSATION. 20 days of letting someone else plan what we will do and while this is NOT the norm for us... we are doing many things we would not normally do. Next month we are going to a pre rally to the FMCA western rally in Redmond OR and at it the "bankrupt" Monaco will fix two items for free plus parts. Fortunately I'm having a hard time coming up with two items.
My point is there is more to this than depreciation, interest rates, Montana LLC, or Fair Market valus. At some point you have to decide to "JUST DO IT" but if you spent a lot of money and find it's not for the DW (or you) then you are going to have a big money hit. Rarely are we lucky enough to buy our last coach first so my suggestion is to buy something used in the $100K to $150K range and see how it goes. While hopefully it will not be your last coach, you will not be hurt too much if this adventure does not work out. Good luck in your search.
