Rich, We have owned our 31 foot 2001 Coachman Mirada for 4 years. This problem just started happening two trips ago in Maine. The black tank almost drains completely when the coach is flat but when we get home and park it in our driveway the back end is probably 1 1/2 foot lower than the front end. This past trip there was probably 2 gallons of black water in the tank which was quite unpleasant to collect in a large plastic container and dispose of inside our house. The gray tank probably had close to 25 gallons of water which I collected and also disposed of it the house. We do not have any children traveling with us just the best black Lab in the world. Following up on the suggestion of the other member who commented I climbed up on top of the RV last night. We do have two vents one for gray and one for black. I took a look at both of the vents, unfortunately the caps over them have been in the sun so long they both cracked when I touched them. However, the gray tank had a very large wasp nest inside of it. Almost large enough to cover the entire vent pipe. The black tank had two smaller wasp nests. I removed all of the nest and did the best I could to put the caps back in place with silicone caulk. I will have the caps replaced in a few weeks. This weekend I plan on putting 10 gallons of water in each of the tanks, take the RV out, park it on a nice flat area and see how much water I can collect from each of the tanks on a flat surface. I really appreciate the comments. Regards, Dave

I have a different problem I was hoping someone could help us with. For out past two camping trips both our black but especially gray water tanks will only fully dump when our Coachman RV is on a hill ( or with the front leveling jacks lowered). If the RV is level only a few gallons of water comes out of the gray tank when we know there is ~ 30 gallons in there. This only started occurring during our past two camping trips, until then we completely emptied the tanks when they were level. Any suggestions?

Gary, Thanks for the advice Dave

We extended our driveway when we bought our 2001 31-foot Class A Coachman Mirada RV. Our driveway is a fairly steep incline. Normally I back the RV into the driveway so it is facing uphill (gas tank in the back). After extended times without starting (three to four weeks), it seems like it is difficult for the gasoline to reach the engine, which makes it hard to start the RV. With an incline driveway, am I better off backing into the driveway or pulling in forward? Thanks.
