On a side note I had an 'experience' when dumping the tanks this weekend. We pulled up to a rest stop dump station and when I went to remove the cap to put on the hose black water dumped on the ground! it wasn't a lot, maybe a couple cups but it was not a fun thing!!! Luckily I had latex gloves on and washed everything down the drain but this should not happen on a new rig! I wasn't happy.
I checked the blade valves when finished and nothing seemed to be leaking but the tanks were empty so I'll keep and eye on it and see how it does next time.
