Considering a rooftop tent for my 2018 4runner.

This will be used almost daily for a continuous, extended period of time (at least 2-3 years) so I need something that will take abuse and inclement weather without problems.

My main concern is weight, as follows:

1 - weight during motion. I have the Nise rack (here on the forums) on the roof. If needed I can buy another roof rack that will fit the tent. My concern is whether the mounting on the rack will be solid.

I watched many YT videos about this and to me, the mounting on the roof seems a bit flimsy. I also saw a few videos showing how the tent simply fell off the roof.

Toyota recommends not to exceed 120 lbs on the roof rails. Most roof tents are over this weight. This will be weight in motion, which adds even more stress on the mounting points. Planning to do about 50-50 offroad and highway driving.

If I go this way, I might find a way to reinforce the mouting. Weight still remains an issue.

2 - weight when stationary. The weight on the roof rails will be my weight plus whatever the tent weighs. Expecting around 400 lbs (tent 150 + lbs. myself 200 lbs). Will this be an issue ?

I am looking to buy a hardshell, top of the line, I am ready to pay for a good quality tent.

Looking for owner feedback. Any thoughts appreciated.

Thanks.
