I would look at the Holiday Rambler new Nautica 34RX
Look like a nice floorplan.
I’m not too sure about a 340HP diesel
But it will fit in many state and National Parks.
Watch this video and just go and look at one

I’m done with even looking for a state or national park for the foreseeable future.
I do fit in my local Army Corp CG and it even has full hook ups.
We do a weekend the last weekend they are open in the end of October.
$20 for a senior camping. Not bad!
I fit in I think 3 sites with the full hookups, but, no one here camps at the end of October except us. So we have it to ourselves.
Ives Run / Lake Hammond it’s beautiful, peaceful and a good last camping weekend in Pennsylvania
