Thanks again for all the responses and experienced advice, and thanks for the specific $$ for toad hookups. Even though we've never owned a Class A, there was one in the family that we drove several times, and last year when we were going back and forth between whether to get another TT or another MH, we looked at literally hundreds of used units online with their floorplans. The floorplan of this Discovery at this dealer is one that we could use for several reasons and there are two more things my wife wants to check on when we see it tomorrow. If those two are a go for her then she will likely want to spring for this one. And it does definitely have the exhaust brake. The salesman didn't know where the switch was, but the manager did.
Last night I did some reading up on the dreaded 53 block from Brazil and this will be the first thing I check for. If this coach has the 53 block then that will be the end of looking at this one. I'm so appreciative that this was pointed out. We can handle replacing a refrig or ac unit or injector pump, etc, but replacing the engine is something that we can't risk, especially on a known issue. Many thanks again to all.
