Hi,
We bought a Blue Tongue Elite rear fold hard floor in 2014. Andrew and Karl are great to deal with and very open about the camper origins and it's ability. They are also one of the few sellers who weigh their campers with all poles, annexes and empty gas bottle on board. So the tare weight on the plate can be more trusted if that's a concern for you.
We had some small quality control issues with the camper but at this price point I was OK with that. None were serious or left us stranded and I've read guys who have spent $60k on a camper and still had issues.
Regarding the canvas, the first time we used it we had 3 inches of rain in about 3 hours and 10 inches over a 5 day period. We didn't get a single drop inside the camper or annexe. So quality of the canvas wasn't an issue for us.
If I was in the market for a FF camper, I'd give them serious consideration.
Cheers,
James
