Hi All! My wife have been looking for a few months for a popup with slide out dinette to upgrade from tent camping. We found a local listing for a Coleman Niagara, it's either a '99 or 2000 year model. The inside looks very good and the floor is solid, all appliances work, crank handles great, etc. However, as is typical with these models the ABS roof is cracked and possibly delaminated. And this one seems to be cracked pretty badly in some spots. Please see my video which shows the corners crack, and the majority of the worse cracks. Can these be repaired? We were thinking of using the Pop Up Princess method of fixing the roof. Will that work for cracks as severe as these? I also have an album in IMGUR for more perspectives. Please help! We really like this one, but want to know if it will be worth our trouble, and even possible, for us to repair. Despite the cracks, water does not seem to have affected the inside of the trailer yet. other videos here, here, and here. Many Thanks in advance for the advice!!
