Our 2014 17b, picked up in September 2014, has the two optional upper tail lights. Last summer in July 2015 we were in Oregon during a heat wave when temperatures reached over 39.5 degrees Celsius / 103 degrees Fahrenheit parked on cement. We believe that during that trip the excessive heat caused the upper tail light lenses to expand and separate from the trailer body.
The ETI owners manual states that it is the Owner's responsibility to monitor all lights and other access points on the trailer to ensure that sealant around those entry points remain in place/viable. We did not follow this direction.
This February/March during our wet rainy season I noted water stains showing that water had run down the back corner over the bed. The foam backing of the vinyl and the mattress were wet to the touch. Water had also soaked into the plywood bed platform. Electrical wiring behind the vinyl became a conduit allowing the water to run into the trailer through the driver side upper tail lights. There was mold behind the vinyl corner piece and along the edges of the mattress.
We took the trailer to ETI where it was in their care for one week. The trailer interior was dried via dehumidfiers, the upper tail lights were resealed, the wire holes to the tail lights were sealed, areas where water had entered the trailer were cleaned (a product to remove mold was used) the plywood bed platform was replaced and the mattress was cleaned using the same mold removal product. The corner vinyl was replaced. This work was done under warranty. We did not want to accept the mattress as is and ETI replaced the mattress with us paying 50% as this was a grey area.
As owners we accept that it is our responsibility, as the warranty states, to ensure that sealant around entry points remain viable. We are pleased with the way ETI handled this issue.
Primary Takeaways - keep a keen eye on all entry point sealants - especially the upper tail lights during heat waves.
