We are happy with our A122S, but would like to find a model with one change. I don't know if it can be done, but I would like to see a cassette potty, instead of a free-standing one, so that you could just open a hatch-door outside, slide the waste tank out for emptying and installing. Seems like setting that potty in at night and out in the AM every day is starting to feel harder on my back every day. Every manufacturer that includes a casette potty eliminates the dinette to get it in. We like having the dinette available. I assume that such a feature might require a high-wall A-frame design, and that would be alright with me, but I can't find one. Anyone know of a company making, or planning to make, an A-frame like that?
Incidentally, the cassette wouldn't have to be part of a shower set-up. I can count on the fingers of two hands the number of times I've used a shower in my trailer in 30 years of camping. It's too easy to use the campground shower.
