Cub Brumby Extreme Off Road

G,day Phil, I do not own one but I would like to direct you to a search on this forum...I read somewhere (If not here) that the Cub has a "Flap" at the rear & has tension on it via two strong external springs I have seen the set up as we were looking at a Cub too. A chap from Sth Aust had one on a trip & stated that when they were travelling through/on a muddy track the "flap" was forced open causing ingress of smelly mud and water. I understand that the idea of this "Flap" is to gain access inside the camper at the rear once it is closed up. Have a good look at it and a talk to the distributor. I am talking two years ago so they may have changed the design or improved it by now. We decided not to purchase the CUB. Regards & happy trails
