My Toy Hauler is setup to carry two Harleys (although I usually only carry one). I use ride in Condor Chocks. I have used a Harbor Freight Chock like the above and for the money that is a pretty good deal. I went with condor because it's quality and the locking bracket that secures the chock to the floor makes the chock removable. You will want to stagger the chocks brackets.
I have three sections of Etrac that run down the sides and middle of the floor. Carpet over the Etrac can be left in or taken in and out. I cut the carpet around the condor brackets...
For heavy street bikes I would double strap the front. For the rear I just cross strap by going through the rear wheel (it's just to keep the bike from shifting..
By hauling the bike to one side I can still use one of the rear couches and part the garage when the bike is in transport..
PS. You don't want to carry your bikes with kick stand down..Can damage floor and hard on the bike too..
