Bike Rack, To Go Please.

I would really like to bring my bicycle along and seriously need to keep working on weight loss. I've seen a few trucks with a bicycle and rack on the back and am wondering if its custom or something i can buy and have installed. I work for PTL and our fifth wheels are locked in place. They can't be moved so i dont have to worry about that. Any body done this? Im sure fabrication would be cake work but I'd rather something i can buy. Pics?

Most company drivers are not allowed to modify their trucks. I saw someone who strapped the bike upside down to the back of the cab.

There are ways to do it, hopefully the guys that do will chime in. I just started to walk my whole 30 minute break whether it be around the truck, rest area, etc. Also try to walk for a few minutes here and there every couple hours or so when driving.
