We are in the middle of 6 week road trip with our 2008 Starcraft pop up camper. Everything has been going great the past 3 weeks camping in it nightly. When we were setting up we noticed the backside was separated from the side. The wood looks a little week but I don’t really want to open a can of worms. We are in California and from Kentucky. A long way from home and our major tools. What’s the best way to tighten back up? Caulk? Try longer nails? Both? Ratchet strap? Duck tape . Open to all ideas. Thank you!!
