Taken delivery and already done our shakeout trip. Absolutely love this camper! So much nicer than our last unit. Has space to actually move around without running into each other. Still learning our way around the camper and haven't had any major issues. However there is one nagging occurrence that has me perplexed. Ever since we picked up the camper. Even before we used any of the waste tanks, there has been a strong methane like smell coming from the camper. At first, I thought we had a propane leak, but confirmed that that is not the case by turning off the tanks, and still finding the odor present. We have been out with the camper once, and used and drained the black and grey tanks, but I have confirmed the smell is coming from what I believe to be the black tank vent by climbing on the roof and doing a smell test. Can smell it if your within a few feet of the camper and the wind is just right. I dont know if I'm just being a little oversensitive and this is typical or if this is something abnormal. I cant walk past the camper without smelling the methane odor. This camper is two weeks old. Any thoughts would be greatly appreciated.
