I installed a Cruiser Ramp in the bed of my F250 and take our 950# Honda Goldwing along with us on our trips south while pulling our 29ft Sunset Trail. I find the five months of snow in Iowa too long to go without riding the Wing.
The Cruiser Ramp has a 12V winch which pulls a cart that has the front wheel of the bike strapped down into it with one large ramp for the rear wheel and two smaller ones for the cart wheels. It takes a while to get the loading/unloading down but now is pretty straight forward, just take your time. I normally don't bother for short trips but for longer trips its a no brainer for me.
The Cruiser Ramp was a bit pricey but I've never regretted getting it, it allows me to enjoy two of my favorite hobbies on the same trips.
