Just thought I would post this up-date on the jacks.
I've always heard that "the squeaky wheel gets the oil"!
Well I've announced the need for the camper jacks and someone came through for me. A fellow co-worker was at someone’s farm and they offered him three jacks from an old camper that had been destroyed by some cows, (I believe that's how the story goes.) He asked him if he wanted them and he said no but I know someone who does. He then told him to take them. He took them home and then after getting in touch with me I went and picked them up.
Now I have the four and I think the project will work well to support the truck cap.
Thanks everyone for looking!
