We have a 1994 Coleman Columbia which has served us well for the past 8 years. However, the water barrier that was sewn into the seams on the bunk ends has been deteriorating and falling out in pieces, which has also lead to increasing amounts of water leaking in when it rains. This camping season I have had a lot of water coming in, to the point where it streams in at times, and threatens to soak the bunks and bedding. It is reaching a point I need to make a decision. I just have not been able to decide which way to go. I suspect the only real fix for this PUP is to go with new canvas for at least the bunk ends, if not a full re-canvas (which from my pricing on line is not much more than buying canvas sections individually). However, my wife and I are torn as to whether invest that much in this PUP or look for something newer. Mostly I have some reservation about putting a lot of money into a 25 year old PUP, not knowing what I can really expect from it for a serviceable life. The positives of this PUP: Tires are in their third year, brakes are in good shape, and bearings are in good shape. So it runs down the road just fine. Lift system seems to be fine, and the whiffle tree has plenty of grease. No apparent problems there. Interior is in relatively good shape for it's age. Some wear inside, but nothing is broken or failing. I have found one of the four corner caps on the roof seems to have seeped some water in too, but I can caulk that up so I do not think it is a problem. Am I overthinking this and should just go with the new canvas and expect years more out of this pup?
