I’m a Keystone (2016 Alpine) owner myself.
Historically, the Montana Alpine, and Avalanche have been the “luxury” or upper crust group of 5ers for Keystone, whereas the Cougar has been a notch lower, but still a nice unit. The lines have no doubt blurred some in recent years and I haven’t been shopping lately, so there’s my disclaimer.
A few areas that will generally indicate a step up or down are…..
1. the “quality” (using that term loosely) of the upholstery on the sofas, recliners or theater chairs. I suspect the Avalanche will be a bit nicer or appear to better appointed. You might also see a difference in the quality and thickness of the mattresses as well.
2. Frameless windows - Avalanche, like the Alpines and Montanas, will have these whereas the Cougars do not. Frameless windows are considered to be the upgrade.
3. (Perhaps the best indicator in my opinion, short of looking further at the frames) is dry weight and gross weight ratings for each on units of very similar lengths. Options and amenities will certainly affect the weight, but generally heavier = better. Avalanche will most probably be heavier than Cougar of similar length and will have heavier rated axles wheels and tires. A quick visual is to look for 8 lug wheels vs 6 lug; Cougar will likely be 6 lug where Avalanche will be 8.
Just a few things that are fairly easy to see or check when comparing the two on the lot.
