I bought a Bushtec Quantum. It came with the lid mounted clothes bag and cooler up front. I bought a spare tire/wheel assembly with it. When we head to the cabin up north for our long weekends (about a 750 mile round trip), packing is a breeze. On our Canadian tour last fall, we became very popular with our friends as they "over bought" their bike capacity...

The Roadstar doesn't have a garment bag for lid mount like the Quantum has available. It does have an analog to the saddlebag or tour pak lid organizer that can mount the full length of its long lid. A lot of pockets for small items there that have become very handy.
I also quickly came to really like just not even having to decide (or even think about) if something might be useful on a given trip or not. Just throw it in the trailer. Did find the same buddy-stowage phenomenon. Other peoples jackets, extra helmet and general stuff is easily collected.
Like the cooler a lot too. But loading it is the only quirk I've experienced. Found out early on that, at least with mine, if it is fully loaded with ice and beverage it'll get the nose of the bike light. Presented primarily on downhill breaking. The nose was seat leather sucking light a couple of times. Once you got used to it and expected it was easily compensated for. Loading the cooler only half or so full solved the problem. But the first time when it was unexpected was an "oh chit" moment.
