Truck bed rack question

[Glyn]

Thanks for adding me to the group. We just got 2,specialized E bikes. Mine is the Vado 4.0. We also have a travel trailer and a Toyota Tundra. We need to get a truck bed rack and probably need to remove the front tires to fit them in the truck. We have a fold back tonneau on the Tundra. That complicates putting rails above the truck bed. Any suggestions?
Thanks for help.
