Is this your camper? This water damage was caused by a small leak at the clearance light. Leaks are very hard to detect, yet will destroy a camper!!! Middleton RV offers a service called "Seal Tech" that detects these leaks and will help protect your camper and investment. Seal Tech allows us to safely pressurize the camper and then we spray all the seals and joints starting at the roof and working our way down. This service only costs around $150, and we recommend it being done yearly at end of season when you're doing your winterization is best (best defense against a leak occurring while the camper "sits" over winter). Think of it as simple maintenance, like changing the oil in your truck. The peace of mind alone, knowing you're not camping in this moldy mess is worth it !!!
