 Is the 'Lance' a brand of RV?

 
Yeah, it's a Lance 1475 trailer, listed as a 2022.

 That adds more detail on what it looks like inside.

 
Thanks for that, I hadn't seen it before.

Figured it would be handy!

I'm now wondering if my best bet may just be to minimize use of
the battery so it might last a couple of days.  The fridge seems
likely to the biggest draw, and is probably why the batterys has
lost a significant portion of its capacity after a day of towing. 
Would it be unacceptably dangerous to run the fridge from the
propane tank while towing?

i'd gather data for a bit.  There are several approaches to this.  What
you want, is good batteries that don't 'leak all the juice out' (lose
charge at unacceptable rate when parked for a bit, not being used).
That means the Ecoflow River 2 isn't a wise choice in a long RV trip.
The Jackery (hasn't had the same test applies yet, patience dear one!)
is a much better bet.  I know it was parked for 3 months once and lost
only about 5% charge.  That wouldn't be noticable.

The ecoflow river (ECR2 for short) isn't a bad battery at all, it's
just not right for this application.  It fits my needs though with one
running DVD/TV (perhaps laptop?) and other used most of the time in the
shed so Don can play with building fishing lures and small wood working
projects.  If he has to stop to recharge it, thats simple.  We can even
bring in a spare portable AC with an electrical cord from the back
porch.  (estimate ECR2 would last 3-4 hours on it's own with an LED
light).

You'd need more power and a longer holding time.  More in line with the
Jackery.
