What's the difference between regular and light 5th Wheel?

KZ has a larger version of my HT. The only difference I saw between the two was mine is 3 ft shorter and without a bedroom slide. The bedroom in the other one was larger and more user friendly than ours.

I didn't notice any "visable" difference in the build quality. Not saying it didn't exist but they both had the same look and feel other than the bedroom. I basically sacrificed the bedroom to be able to tow with my F150.
