Just a thought, while 'you' may not care about a curtain wall, make sure the wife is aware too. My plan after our first popup was a bigger one with toilet and curtain. It was at this moment that my wife proclaimed she will NOT use a toilet with only a curtain wall if I'm in the camper. Well, if one of us has to leave then I suggested putting it outside in the shower tent. That went over like a lead balloon. It led to us getting a smallish 19 foot TT with a slideout dinette, full bath..etc. Which then led to our new 26foot bunkhouse. It's a slippery slope! Have fun!
