I was at the dump station at Ludington State Park on Monday, looking to get a good dump of all three waste tanks for the final time of the year before winterizing. I pulled out my Lynx Levelers in preparation to lift the door side of my TT to try the maximum gravity assistance trick in dumping my black tank.
A fellow camper with a big 5'er was at the next dump island and saw what I was doing. He suggested I instead use a tiered ramp-type one piece leveler/jack he had with him. I borrowed it and it worked great! I've never had that kind of flow from my black tank. It barely required a rinse with the flushing system.
I wish I'd seen the product name on it, because I'd like to buy one. After an internet search was fruitless, I can only say it was generally comparable to the yellow Camco RV Tri-Leveler found on the WalMart website:
Camco RV Tri-Leveler, Yellow - Walmart.com
The one I borrowed was also yellow, but appeared a little beefier, and may have even been taller or had a fourth level. Does anyone know of or have something like this (other than the Camco version) which you could cite by name and source?
