looking fiberglass seems much harder to DIY. No slide will reduce interior space, but free up another thing that can go wrong.

Weight looks good. Tanks seem ok. I can't comment on the frame/build quality from the photo. Floorplan looks useable, It'd be one I was interested in if I were in the market again. It checks a lot of boxes.

We use ours 10-14 nights a year, so I'm in the "I enjoy Trailer Camping" camp, but I would never recommend one if you aren't going to use it 10+ nights a year. Just rent, you'll come out ahead.

Get a rear camera. Make sure it's a "driving" rear camera and not a backup camera. They have stronger antenna and better refresh rate. They are also around $300 vs. $150/less that you see on Amazon. It's a game changer.
