Best tent is a $50-100 tent at Walmart that you can throw in the bed of your truck when needed and in garage the rest of the time
If you actually do any offroading, adding 200 pounds to the highest point can make vehicle unstable. Plan on damaging it on tree limbs as well. Also creates a lot of drag on highway.
Once you are over 45, and have to pee every few hours, climbing down the ladder in a hurry, in the dark, is a recipe for disaster.
My neighbor had one on his off-road trailer. Basically a small truck tool bed with rack for bikes, kayaks, and tent on top. Used it 2x a month for 2 years. Finally sold it after his wife fell coming down the ladder. Bought himself a Jeep trailer that is only one step.
