Thanks guys for the photos and links. I want to be able to use trailer for more than just hauling planes so I've decided to set up the inside to make it easy to use the trailer for other purposes. Global Jet Club used to sell the "Jet Transporter"

but no longer sells them. This would have been a great solution. Being a modeler that still builds, I've come up with solution to make my own "transporter". I purchased a garden cart

and will use it as a base to make a three-tiered transporter. I'll be able to roll in and out of the trailed and the planes can stay on it for storage. I'm going to install some Etrack to secure it in the trailer. Once again, thanks guys for taking the time to respond.
