Thread: Roof top tent on the trailer

The main thing I would be worried about with weight that high on the trailer is the risk of flipping it on rough roads. I know our camper can jump around alarmingly on rough tracks, and it has a low center of weight.

Otherwise it has to be more fuel efficient that having it on the roof.

Cheers.

Yeh. I was a bit worried about that but apart from the tent, I've kept all other weight as low as possible and also use a Hayman Reece load transfer hitch on the draw bar. I'm keeping the trailer under 500kgs so the hitch is more about transferring weight from the Disco to the trailer. The hitch should also help keep the trailer level.

Happy Days.

Oh, and I'm glad you're more worried about my trailer rolling than me putting my family in boxes. LOL

The aerodynamics of rooftop tents are best if the tent is mounted as far to the back of the roof as possible. There is an article about the aerodynamics of Land Rovers here:
Wheel on Bonnet = Aerodynamic improvement

I had a cargo pod mounted on roof racks on my Subaru Forrester. Initially I had it mounted too far forward. Upon moving it back about 30cms I got an immediate decrease in fuel consumption of 1L/100km. So location of these roof-mounted objects can make a lot of difference.

Well it wouldn't go back any further. It was already right over the back door.

I had my trailer flip over whilst on a LROC trip many years ago.

There's an application for the iPad (called W/Tunnel Pro) which models airflow in 2-D. I used this to select the best location for the pod by drawing it at various points and seeing what effect this had on the overall drag coefficient.
Maybe you could try that to see if an intermediate location might improve matters. While only a rough model of the real airflow (no 3-D) it might give you a clue for the best location.
Like others I'd have reservations about mounting it on top of the trailer due to the potential for it to tip the trailer over in a tight corner. If it wasn't for that it's a great idea.

Putting a Roof Top Tent (RTT) on a trailer is something I also am considering , but I'm interested in finding out how these RTT are in the wet and whether folding up wet & then unfolding them ends in u having a wet bed ??

The plan was for the missus & I to be in the RTT & the kids to be in a 30sec Tent..... All this on our 7x4" Gal Box Trailer with Slipper Springs.... which I don't know if its the best/simplest setup ??
