I was parked up overnight next to a smart looking Land Rover which had a roof tent.
2 am got woken by the occupants climbing out of the tent in the wind and rain, getting soaking wet as they climbed down the ladder and ended up sleeping in the back of the Landy!
Yes had a similar situation in mine you need good wether and sheltered from wind, was in cornwall on a hill campsite wind rain, and I was drunk and had to pee, the ladder hurts you’re bare feet
Pro’s
Extra space
Super comfortable as mine comes with memory foam mattress, and it has plenty of vents and insulation,
Cons
Putting it on is a faff, be careful not to scratch the roof i use the plastic protection sheets from Screwfix and a blanket works well
In summer if you go to sleep at 3 am and you want a lay in, as soon as the sun hits it it becomes an oven, I’ll throw a reflective sheet over next time
Storage it’s big I mounted mine down the side of my house wrapped in a sheet
Handling
The weight on the top is a lot you can’t drive like a t**t, as it becomes top heavy even with bilstien race shocks
Flappy
Some times when doing high speeds as I don’t hang about the awning sheets come out and flap about and t
You have to stop and tuck them back in, fine if you drive at the speed limit, you can’t cruise at 140 (if you’re going on autobarn!!!! Lol)
I put it on last summer was on roof for a month, my can was lowered too much and the extra weight and handling gave increased wear on the rear tyres inner track, bald as!!!
