I can't remember which model I used but it works good on our Uhaul
. I'm away from home for the weekend, will look it up when I get home. The Uhaul
has a raised section there on the roof and plenty of thickness for the screws. Like I said on tnttt, I had to cut down the vertical part of the inside trim ring. I may still have that piece to measure. You would only need a low profile lid if you have a clearance problem, like moving the trailer into a garage.
