I am new to camper and know nothing about them. I have a person wanting to sell me a 10 foot 1977 Starcraft pop up for 300 buck. It has a few problems. . The corner of the back wall is rotten and is pulling way from the side walls and needs to be braced. I really dont know that that means and there is a tear in the cavas . I seen pic of the camper it looks ok but I want to know if these issues can be repaired. I am just looking for something cheap to find out if we even like camping or not. thanks your help is needed.
