No need to rent vans or trucks for a bike unless you have a hard case.
I have a soft Pika Pack Works bag. I put my Seasucker rack in the bag if I think I’ll need it. Bike can go on the roof or truck of any sized vehicle and the bag can roll up small enough to easily fit in the truck with other bags.
Saves money on bigger rentals. Especially since many credit cards won’t allow their insurance to be used with pickup trucks.
