This is the Lance we had. Yes that is a slide out on it.
It was able to be free standing on it's own. Some of the TC aren't capable of that. The floor isn't strong enough to support you when it's not on the truck.
This one has a slide out on the curb side, 3 way fridge, AC, generator, and a 80 watt solar panel. The bed over the cab was a queen, and it runs length ways with the truck. It was very heavy. I had air bags and needed them.
It was for the short box (6.5 ft.) and that is what we had.
We toured a lot of the US with that rig.
I thought I would add this info but keep it out of the classified section.
