Pat you have mail, one of the pictures that will be posted later.
Actually no, I have a half tank of water, but the more water the lower the center of gravity would be as it is below the floor and directly over the axle, everything else is trail ready. This trailer works better than my box trailer did, and I was taking it down Black Bear Pass last year, but it was closed while we were there. I think this one could make it. Width is my only concern.
Found out there were actually bets on the trailer not making it 100 yards up the trail, others thought ten minutes or at the first turn around area. No one gave it a chance of getting to the top. There really was nothing to it. You just have to remember to drive where the trialer is going to go and deal with it as you progress. I have some great photos, just getting them to post is the problem.
Many of the guys had driven the trail quite a few times. A box trailer owner said he would not take his trailer on this trail, as he was sure it would tip over. Having a tent on the top adds a lot of weight high. Pretty much amazement all around. Truly had a ball, fun watching peoples faces when the trailer goes where they know it won't/can't, but does.
As mentioned earlier, I am sticking with this design, even if the RV company says no. I can deal with my goal of one a month, it will be more fun that way anyway. Getting to meet new people and working with them to build what they want and need. As Patti just said, for it to do what we want and expect to it can not be wider in the sleeping area. Mine is 50 inches wide at the top, another ten inches and it would have had major scratches from Manzanita bush and rock scraping down the side. Not worth it. If you can not sleep on a tempurpedic, you were not going to either way.
