Yep, That's just how I did it on the box truck. I found some old shag carpet the has a good R value.
Are you installing a truckmount or just hauling floor machines?
What are you going to put on the Floor?

it shows a few pics of the trailer truck I had....the outside of the new one, and the inside of my box...
I think I will just be painting the floor...with what havent decided yet....if you are talking insulation...i never have...but maybe next year if i have a few extra $$ i may get it sprayed as well....
Most of the time it seems i change set ups...(with some over lap) about 3-5 years...(as my work type changes) But this one I plan on keeping at least 10... So i will take my time on somethings to make sure they are right...like the insul.... will take pics to show what i mean..
So mostly because its mounted, it will be setup for TM...
i wanted all carpet stuff on front half...and floor stuff rear....HOWEVER...because that will put my tongue weight WAY TO HIGH... sooooo i will need to stagger like in the box truck
