We currently have an 2011 Arctic Fox 1150...have toyed with upgrading now that I have a new 2016 Ram 3500.
What would I do differently? Not much, likely end up with a new AF 1150 Drybath again...
New would give us all LED lights.
Electric rear awning would be nice.
I would put a Fantastic Fan in the bathroom besides over the bed.
I would add a side awning too.
I would still do a built in genny. Great for making coffee first thing in the morning.
I would still do the microwave and oven.
We use the microwave enough to be handy and it works well as a bread box and holder for bags of chips.
We use the oven for casseroles and side dishes.
I would add solar panels.
