RE: Bronco 1251
We've had our 1251 since January 07. Agree with pp's it's basic but so much better than a tent and has worked well on our shortbed with airbags. I also agree with the extra caulking/putty. It appears excessive if not sloppy on ours.
RE: If camper doesnt have grey water tank were does it go??
On the underside of our camper there is a spot for us to connect a hose that then is put into a water jug outside the camper on the ground. We dump the water then when we get home.
