I thoroughly enjoy my roof top tent, sleeping in it is very comfortable, the mattress is a memory foam job..... I have to agree it is expensive, even with the smoking deal I got my used one for. We slept at elevation in the Rockies and were quite comfortable inspire of the freezing rain and heavy frost each morning. Additionally the trailer offered an easy way to have comforts that would have taken up to much space in the Jeep. My akita has pretty much the whole back of the Jeep when we are wheeling or just driving, but at camp we still have very comfortable chairs, a home made skottle for cooking on as well as a decent stove, 21 gallons of drinkable water and an on demand hot water heater for showers....... it is worth it to Lucy and I
