How do I do it - is there a way?

You could put the front of the camper on the bed (remove the jacks) and use some thick dowels between the bed and the camper to allow your truck to "roll" under the camper. Then when it's in far enough you can reattach the front jacks. Of course this isn't easy but it's doable. I've done it. It's obviously far from ideal. Or if you had some furniture dollies those could work too.

When I did it, I had two buddies on the back corners to help stabilize it and aim it as I backed under it. Probably the most nervous I've been since my wedding.

How long does it take to install the swing out brackets?

I'm going to need the brackets eventually, but I don't know if it's something I can install at the owner's home, what tools I'll need etc. I was hoping to be able to back under as far as I can, remove the front jacks, then jack and slide, etc. Is there anything I could put between the camper and truck to make this feasable, or would it destroy the camper?

Not sure what brand the jacks are - does it matter?

X2 what egarant said

borrow or rent a truck for the ride home ,then figure your loading arangment later. put it on a flat bed trailer,sit down think this thru, so it gets home in one piece.

Have a crane pick up the camper and drop it into your truck bed.

Other than that, you need to purchase a pair of swing out brackets, after all, you will be using the truck with that camper, you will need them anyway.
