While there are plenty of companies who will take your money for products to add to your black water tank, NONE will make the smell appetizing. And many are harmful to the environment, particularly to septic systems. The object is to have it vented such that the odors do NOT enter the coach. The "wind seeking" vents do work to better vent the tank out the roof vent-- creating a slight vacuum at the roof vent, such that odors are less likely to enter the coach. Are you sure the source of the odors you smell is the roof-- that is unusual. That is where you WANT that tank to vent (vs inside the coach). More common causes of odors in the coach are bad seal at toilet base or loss of water in the toilet bowl and broken or obstructed tank to roof vent. It could be loose at the tank end or have an insect nest at the roof end obstructing the proper venting of the tank. Brett Wolfe

You have already addressed the most common cause of lukewarm water, and that is a water heater bypass valve that is not completely closed. Also, check for any shower that could be turned on at the controls, and turned off at the head. That will allow hot/cold to mix in your system. When you do run the water heater, does it run the "normal" length of time to heat the water -- i.e., do you think the water is getting up to temperature in the tank but not getting to the faucets, or does the water heater shut off after too short of a run time? What brand/size water heater? Brett Wolfe

For an excellent factual discussion of the factors affecting performance and MPG, go to: https://ohe.cat.com/cda/files/287140/7/LEGT5364.pdf The document is "Understanding Coach (RV) Performance" and was written by Caterpillar Corp, but applies equally well to all engines, as physics is physics.

In a 30 amp male to 50 amp female, the connections are: 30 amp neutral to 50 amp neutral. 30 amp ground to 50 amp ground. 30 amp single hot is tied to BOTH HOTS ON THE 50 AMP SIDE OF THE ADAPTER. So, both "sides" of your 50 amp cord and coach are hot. You just need to be careful not to exceed 30 amps total draw. This is a LOT less power than the TWO 50 amp hots (100 total) in a standard 50 amp circuit. Brett Wolfe
