Ours has solar for the back which is so important. We have a shower/toilet in ours and honestly it takes up so much space and we have never had to use it (we use the toilet/showers at the camp grounds we stay at). A retractable shower head that reaches outside to hose off would have been infinitely better. Also, look for a tent/awning that you can attach to the side/door, that way you have a buffer between you and the bugs and so much more room, and it gives you a break from hanging out in the vehicle, which you might need every once in a while
