Hah, what are us 2016 and earlier guys going to be yearning for now?
EDIT: oh ya I see the radiant heat, posted about that a few months ago.
Few other adjustments I can spot:
The main control area by the front door is all in a single panel. Not sure if that is a good move, as those tiny buttons are harder to manipulate. ie: with a regular dimmer switch it may take 1 second to adjust, on that it may take 5.
Light controls on one side of the sofa.
Kitchen counter top has a backsplash gap to let radiant heat rise.
Interested to know how the radiant heat, heats the tanks if at all or do they have simple heat pads (may not be as good for cold weather as the LP furnace).
The dinette seatbacks are now removable and provide the over table bedding.
The tank monitoring system seems to be much upgraded, although the radiant heat control panel isn't integrated and has it's own control panel next to it.
I do see the dinette table lowering/raising is easier to access on the new control panel, it does have electric heating pads for the water tanks.
Combination control panel under the overhead cabinet above the bed.
Tower warmer in bathroom.
External solar plug by battery box.
Mounted factory solar longitudinal with the trailer and not lateral.
TV antenna is different.
Hot air exhaust for the LP radiant heat air handler that is located under the front dinette seat. Air exhaust is just outside at that seat position, just forward of the exterior shower compartment.
Thats the changes from what I can see in the photo's.
It will be interesting to see how well the radiant heater works and the usability of the centralized control interface system is. I plan to mimick a lot of the radiant heat idea, but with cheaper electric strips.
