I haul two full dressers in our Seismic Wave. I know that it is possible to strap a bike down using 4 straps pulling 2 forward and 2 back, but is this an area you want to save money? Your bikes and trailer cost you a bunch of money, so I wouldn't nickel and dime this. I purchased 2 Condor quick release mounts on Amazon for around $210 each. I mounted 2 bolts and a very small metal plate into the floor of the toyhauler garage for each bike. When I drive the bikes in, I don't have to worry about going to far and I'm hands free to strap them down. When not traveling, I regularly use the stands in my homes garage as well.
