I have a 2018 Cascade on 2018RAM 3500 CTD Dually. I have never owned a Lance. It rides better than my prior Host Yellowstone ( 2 slide). Better stability and Center of Gravity (CG) feel. I only have lower stable loads, no other mods on new truck. Still stock tires.
It is a somewhat non-traditional floor plan from my prior Host. I can tell you that it is much more comfortable however. My configuration was ordered as a king size bed, one recliner and the sofa w/high low adjustable table. This beats a traditional dinette hands down. Pecan interior with simulated leather on sofa and chair. It can function as a dinette a living room or a mobile office . Installed sat radio antenna at the factory and we installed the radio on fireplace mantel after. We have taken two long trips in it including almost 3 months up the eastern US and into eastern Canada this previous summer. It is a very comfortable camper and we really have enjoyed it.
Tank dumping in a Cascade is non-traditional and not like my other camper and was my biggest transition issue. The black tank is in the slide and is dumped separately from the gray tank. You will need a longer hose. It is important to keep your dump valve cable lubricated.
You must open both slides to access the bathroom. That seems to be an issue for some but we have not found it to be a problem.
Hope this is of some use.
Cheers
