What do you think? Suggestions?

I have been thinking and tinkering for quite a while now trying to determine exactly how I want to build my tear. I decided on the Benroy,I have cut my profile, but I haven't decided on everything I want to do with it. My first decision is about the chassis. This is where yall come in. From the very beginning I have wanted storage under the floor but wasn't sure how I wanted to do it. I have a 5X8 utility trailer with the 1 foot tall angle iron rails on it. Initially I was going to cut the rails off and sit the tear on the floor of the trailer. My latest thought is to leave the trailer rails and sith the floor of the tear on top of them, leaving that 1 foot storage space under the tear. I would probably drop the galley all the way to the floor of the trailer to keep the counter top from being too high and make some access doors on the sides to access the storage area. What do you think?
I have tried and have had zero success with the cad programs, I'm good with pencil and paper. If someone could draw something quick and dirty yo give me a visual of my thoughts and your interpretation of them I would greatly appreciate it.
Thanks for your help and opinions.
