I've got to ask -- if you don't use your sofa, where do you sit?
On our butts of course...

sorry...had to...
I am pretty sure we use the camper much differently than most here.
We dont sit much, if at all, in the camper when it is in 'festival' mode. Its really much more a master suite. If we are inside, most of the time its in bed. Or in the bath. We dont cook in there, nor eat really (unless it is HOT out).
Check out New Year's setup -
https://forum.phoenixusarv.com/index.php?topic=3031.0 4 day stay. Nice and cool, didnt rain until we were packed up anyway.

The outer area under the awning has a couple chairs and small tables. Outdoor Camp Chef oven and stove combo on a 2x6 folding table. We do our cooking and eating there. Camo netting around it with tapestries allows for a breeze, but is VERY private. The awning has the big angle to shed rain, and is roped and staked down to prevent loss from high wind.
The 8x8 beige tent is like an airlock, and protects from things wandering away.

It is the only entrance to the under-awning area. We had a small raised firepit and had a fire going near the entrance , with two of the larger recliners set up. We spend most of the time at the stage(s) , so it is VERY nice to have the 'airlock' as a visual and physical barrier.
This is our 'small' setup, for when space is limited.
For our WANEE and other larger fests, 5-12 day, we add a 13x13 popup behind the camper, and have a bigger camp kitchen and seating there. At WANEE we cordon off ~ 1/2 acre+ with camo netting, and have several campmates in their own tents. The 13x13 is like the mess hall. There is usually someone there at any time, so things are a little more open and communal 'in camp'.
So.. the coach never really gets 'living room' duty. We *always* have had stuff stored on the couch and behind.
Since you and Ron both have 2350's without slides, maybe Ron has some insight as to how practical it may (or may not) be to consider this swap.
The cushion color isnt that critical, as there are no other seats to match.
1800 mile round trip is a consideration. 2 day out, stay a day, 2 day back. A couple days off work, and $650 in gas.

Have to think this one out.
