If dinette gets in the way - remove the dinette.
Sometimes I forget that many people (most) are younger than me, there are more than 2 people in trailer, different issues. So I won't be preaching much. Still...
When the only place for cat heater is in front of dinette near door:
.
Red extinguisher is near the door. The heater is actually in front of (missing) dinette bench. Bold spot is where the front bench was. Removed the bench temporary to run the propane line, and was amazed how much space I gained, and how much more comfortable and versatile the chair was, compared to the bench. Easy to get in/out of the table, nothing to bump into when walking. The bench was already cracking where it was attached to the wall - after 2 years with just me in the trailer. Donated it to local villagers on seasonal camp. For travel the chair is wedged between the table and the other dinette, or stored under bed.
Resale value? Doesn't matter after 5-6 years. When looking for a trailer, I saw this in relatively new rigs - people removed one of the benches. Here in DIY forum there are photos of mods with both benches and table removed in trailers and motorhomes, IKEA or Lowes pieces installed. It all looked nicer, roomier, more comfortable than OEM dinette. There are probably very few rigs where dinette is designed and placed well.
Clear cover on a cat heater is not a nice touch but a necessity in windy and dusty places of SouthWest. Catalytic pad and dust don't go together well.
