Hoppe,
Re: Tripp'n Out.. heheh
I'm not sure if you were asking me or other posters, but in my case, looking for the Cargo trailer to house a Polaris Buggy, ACE and with luck another XP1k.
As I think about it, it will store additional items, fuel, water, canopy etc but not going to be a 2nd room per se.
Toys work better without the "Un-intended" dust/rain/wind and helps keep them from "Wandering Off" Plus, if I would need to separate them from the "Mother ship".. it's a little more secure.
So, for me, the Cargo trailer is for the toys and additional storage as needed..
Hope that helps, if you're addressing the other helpful posters, you might try a PM to them...
Happy Trails...
