Has anyone changed their seat post for a suspension post? Any recommendations?  I've been looking at the Suntour, but the Kinekt looks nice too.  Any problems with the seat hitting the trunk bag behind it?

Both my wife & I each bought an Expand5. We also happen to be considering a new mid-sized SUV, and would like any feedback on which ones work well, or don't work well to transport these folded inside instead of a hitch-mounted rack.  I have seen mention of using a 70 gal tote bin, which look bigger than expected. I'm not sure many of the SUVs will fit two of these inside, even with the rear seats down.   Any recommendations?  Thanks!


UPDATE:  We ultimately bought a new Hyundai Santa Fe and couldn't be happier how it can fit both bikes side by side with a lot of cargo room left.  The vertical and horizontal clearance exceeds most of the other mid sized SUVs we've looked at.  We load our bikes onto shallow plastic bins instead of a tote; they slide in easily and take up less room.  These are sold at Home Depot or Lowes as concrete mixing bins, and we stack two together for each bike to manage the weight.
