We just competed a trip to Denver and back using our Roadsterbag luggage set.
Bottomline upfront, we were quite happy with it and it worked as advertised.
We would be spending two days and three nights in Denver, with a total of four days including travel. What we were able to pack in each of our trollies:
ME: two sets of shirts and shorts; two sets of slacks and shirts, for four complete outfits before mixing and matching. Six days of underwear and socks, and a pair of dress shoes. Two sets of t-shirts and shorts for bumming around the house/exercise. A large man's shave kit and my laptop computer with accessory cords for computer and phone.
HER: Skirt and two slacks with blouses (three complete outfits) that mixed and matched for 6 outfits. Bathrobe and four sets of undergarments. Two pairs of shoes, large makeup bag/toiletries, and a hair dryer.
In both cases we each had a little room left-over. The trollies fit under the cover for top-down driving if desired. While we didn't use it, the small case would fit on top of the trollies if the top was up. Plus extra shoes and heavy coats could be placed in the boot if the top was up. We could have packed a light coat each in the trollies if needed (90ş+ temps made any coat unnecessary). The laptop could easily be placed behind one of the seats, freeing a little more room.
The cases themselves are very well made. They all have a zipped-in liner that is removable for cleaning. There is a mesh pocket in the lids for dirty clothes or other uses. The cases rolled very smoothly and the handles extended and retracted like butter. They are fitted with interior clothing straps. One small issue is one end of the straps is too short to flip over the side of the bag to keep it out of the way while packing. As you pack, you need to find that end and position it so you can access it to secure the straps.
We used a clothes' folding technique that worked well to make each item small and easy to pack. The roller cases are deep, so we put the small items (underwear and the like) on the bottom, then layered the other clothing on top. If you plan to live out of the bags, it was easy to remove the layers (keeping them folded) to access what was needed, them replaced the layers. Or one can use small clothing bags to organize your items so you can access what you need without having to redo the packing.
One comment I have read about this set in this and other threads is the cost. I wanted a luggage set that looked like it belonged to the car and this set does that. It is well made, solid, attractive, and smooth in function. I wanted hard cases and trollies, so soft-sided bags didn't fit the bill.
My day was made when a friend of my sister saw the set as we were loading the car and remarked 'that is a good looking set of luggage', to which my sister informed her that it was fitted for the car. She relied 'Wow, that is very fancy'.
