We are also a couple with no kids, two legged anyway, to consider in our RV purchasing. Because we didn't want a family "sleeps 6-8" unit we ordered ours. Our 2400W is maximized for us, not the next owner.
Hopefully you are going to enjoy your RV for a few years so get it the way you want it. Come trade in or resale very few options make any real difference in value. Also since most dealers order their stock unit heavily optioned, more margin in the deal, the sales person will often push selling whats on hand rather than what you can order.
To me outside TV's are just a theft / vandalism issue waiting to happen. They are also generally ridiculously expensive options for what you get. If you really need a a TV outside you can move one.
Bunk or TV console? We ordered our 2400W to get the entertainment center instead of a bunk. We don't need the bunk and wanted the extra storage and larger TV. If no one, besides us, wanted rid of the overhead bunks it wouldn't be an option!
Double refrigerator? Only you can decide if you need it... In my experience we never have needed one.
Any sales person selling a monthly payment difference needs to be watched very carefully. You are being encouraged to purchase things you may not need that will directly benefit the sales persons commission. While I do not consider sales people the "enemy" I count very few of them as "friends" looking out for me!
If you want to maximize your trade in value take good care of your coach and maintain it well. Keep your service records so you can show it has been maintained properly. That will help the trade in, or private sale value, much more than any added options. So buy what you want, not what the sales person needs to sell.
