Dumping into the Blue Tank
Has anyone come up with a good solution for connecting and discharging to the blue tank. The sewer connection on my 2000 Excella 30' is too low to the ground for a straightforward gravity hookup. I can discharge almost all of the tank by simply laying the hose on the ground and then letting it arc up into the blue tank - but - the blue tank (30 gal?) is smaller than the trailer tank and, if you try to cut the flow to avoid overfilling, or simply when you're disconnecting, it's hard to avoid a spill. If I get it right, the amount of liquid left in the hose will just allow me to disconnect at the trailer and then hold the hose up to drain into the blue tank. (Not real easy with the trailer valve closed - due to the vacuum created!) Most of the time I simply make a couple of extra trips to avoid overfilling the blue tank. I have had the occasion to use the blue tank to dump the black tank (---sort of a semi-emergency situation!!!) - but I'll agree that most times I would just as soon break camp and take the trailer to the dump station instead. I've gone so far as to even consider a permanently mounted macerator pump.
So far, I haven't had any problems with the wheels and axle on the larger blue tank that uses the front swivel wheels. Others had expressed concern about the wheels.
