It's Sunday, give it time..., folks are returning from camping
I'm not that familiar with the newer Highland Ridge products to provide a good detailed response other then they are 4" wider (100") then the Jayco models (96"), which has some advantages (i.e., space around master bed, etc.).
Looked at them a few years ago and thought they were better then most, possibly at par with Jayco in some comparable model lines. I believe at the time they used cable system slides, not sure if they still do.
