Compared to a tent, the R-Pod will seem wonderful! We had an R-Pod 173 (no slide either), but found that the lack of storage, and nowhere to add any, was frustrating. Also, b/c it's a TT, you will take a hit on your gas mileage - pulling a sail into the wind.
We ended up getting our Aliner. Yes, it's small too, and doesn't have a bathroom (some do have potties/showers, btw), but it tows like a PUP, which is great for gas mileage. Also, there are counters that we can set Sterlite slide-out drawers on, once we get to the campground (stored under the table and bed while traveling). We can fit 5 of them high on one of our counters, and still have another counter to set the tv and other things on. We keep clothes, kitchen stuff, towels, etc. in these. We still have to keep our hang up clothes on a rod in the back of the Pathfinder, but no biggie.
We have a porta potty and use the campground showers. Since we stay mainly in state/corp parks, we were used to using the campground showers anyway.
Just some more information to confuse you - lol! Good luck with whatever you decide!!
