My 2000 Niagara takes a very firm push on the left side to get it closed enough to engage the latch. When I get it latched it will come unlatched presumably due to the bouncing around when driving. The previous owner told me to close the slide out last which I read is improper. I'll try to close it first but I'm not sure that will change the effectiveness of the locking mechanism. We have a trip coming up this week. What are some other fixes I can do temporarily? I've thought about putting a couple of ratchet straps around the entire camper vertically. I've also seen others use sliding bathroom door type latches. Another thought is bolting a dog leg bracket to the frame to not allow the slide out to come out. Not sure which method I will use. I'll first try to setup and camper and close it slide out first. If that doesn't work I'll have to use one of the other alternatives.
