Hi,
Yes, this horse has been beating a time or two before! LOL
I'd just like to make a few comments and questions for you.
First, I'll say that the floorplan is probably the MOST important thing for the majority of RV'ers. Once you're parked, that's what's most important as that's where you will live. You want to make sure that it works for your expected use. If you'll be stopping at rest stops/Walmarts/Flying J's/etc. for sleeping while on the road, make SURE that everything you need access to is available when the slides are in. You may not be able to deploy your slides in such areas.
If you're going to do A LOT of travelling, the DP will invariably give you a better experience. That said, we've done fine in our gasser. But I've been warned never to test drive a DP unless I'm going to buy one, as I'll never be happy with the gasser again. Knowing me, I believe that could be true! LOL
What are you plans for towing a vehicle to get around with once you arrive at your destination? You have to make sure whatever chassis you select has adequate towing capability. This might require some investment in your current vehicle to make it towable and/or purchase of a different vehicle.
Personally, about the time period you mention for the newer, used gassers, RV manufacturer's seemed to adopt a "dark theme" for the interiors of many RV's. Both my wife and I dislike the dark color schemes. I've noticed now they do offer some "white-wash" look lighter shades, but I still don't like them as much as the lighter, natural wood shade we have in our motorhome and those manufactured back in the first decade of 2000. I knot that's personal, but it might come into play if you're not crazy about the "dark" look. (I'll admit, my eyes aren't the greatest, which is why I LIKE it fairly bright in a room when I want to see something. The dark interiors just aren't conducive to that requirement.)
The other thing I've noticed is that the "newer rigs" seem to have way too much "technology" in them for my personal preference. I come from the era of wanting a button, knob or switch for appliance controls. I don't want to reach for my phone or a tablet to adjust the thermostat. Some like that convenience, but for me, it's an extra complexity that is likely to cause problems down the road. And then what do you do when the "app" is no longer available for your latest model phone? Computers have their place, but aside from my personal devices (and the engine & transmission), I don't really want them controlling stuff in my RV. Again, this tips the scales toward older units if it's a concern of yours.
On Edit: Ok...I just read your latest post about Fivers. Disregard this paragraph!
😉 As for getting a Fifth Wheel as you already have the truck. But is that truck capable of pulling a Fifth Wheel which will satisfy your needs, and what's it overall condition? Will you have to trade it in for another? I know people with Fivers and they love them as it works best for them. (Though, a few have mentioned they'd probably get a moho if they could). I can see the advantages of one for many people. But while travelling, the motorhome is so much more convenient. Everything is at your finger tips while on the road. In my opinion, it is the BEST way to travel, especially if you're travelling with a family. The level of convenience while travelling in a motorhome just isn't possible by any other solution.
IF we ever decide to change our first & only RV purchased new back in 2004, it most likely will be with a gently used, high-end DP from the early 2000 vintage period. They are out there, and I believe you might be able to find one in your price range. For $75k now, you should be able to buy a rig which cost over $500k new 20 years ago! The quality in that used high-end rig will be apparent as soon as you step into it.
Good Luck in whatever you decide.
