Lot has changed over the years, pulling a boat with an eight foot beam, plenty of space to put bikes inside of the boat. Saw a Schwinn roof rack for four bikes, actually was made in Madison,WI and quite a bit cheaper to buy it from them as opposed to a Schwinn dealer. But the trunk was so huge on my 73 Fleetwood, could put it on there. Before this, attached two vertical 2 by 4's on my utility trailer with a cross beam on top so I could strap the bikes to that.
As the family grew, got a motorhome with real bumpers, remember real bumpers? Attached bumper type bike racks to that and could carry up to eight bikes, had six kids.
Modified that strap on bike rack to fit on the spare tire of my motorhome, only carries two bikes, but when my youngest daughter came alone, plenty of space to put hers on the inside. It's hanging on two straps from the roof rack. Modified my old Schwinn roof rack to fit on top of my Supra to carry my wife's bike and my three wheeler. It does have a Curt 1 1/4" hitch on it, so could carry four more bikes on that. Since Curt is made in Eau Claire, WI, called them for a special price.
https://www.etrailer.com/Hitch-Bike-Racks/Thule/TH934XTR.html has a four bike rack that fits either the 2 or 1 1/4" hitches, but a whole bunch of these are available, kid purchased his from Walmart.
Not only a bike rack, how many bikes do you need to carry? Ha, no fun biking by yourself, use to having a crowd with me.
Cruze? Just left that alone, ha, even prefer using my Supra for hauling my grandkids, a heck of a lot easier to put baby car seats back there. Just purchased the Cruze to save on gas, that is the most of our driving.
