We built the Falcon Model from around 2000 - 2006, (+ or -).
Small camper, only 60" long (5' feet).
Biggest question ... what year, make, and model truck do you have ?
The Falcon Model was "bolted" to the truck bed (no internal tie downs), so really designed for the older Tacoma trucks with the metal truck bed.
If you have a 2005 - 2016 Toyota Tacoma, you will need to use external tie downs to attach the camper to the truck bed, and the camper will NEED to have at least the "jack brackets" for attaching turn buckles to. You might also need to shim the camper up -- add a small platform under the camper if your truck bed is a bit deeper than the camper base.
The Newer Tacoma's (2005 - 2016) trucks have a plastic / composite truck bed, so we don't recommend bolting the camper to that.
Tork-Lift makes some easy to install external tie downs that can work great.
Hope this helps.
Feel free to call me if I can be of help.
I was out of the office for the last week at a show, so I'm trying to get caught up with e-mails and messages.
Thanks : )
