Dan and Harvey,
Yep, from the inside, though I can still squeeze stuff through spars etc (no roof yet...
And, yep, floor already finished and would like to NOT put holes in floor to hold chocks etc. However, the flexible/bendable thing made me think of using my ratchet straps through the doors and around front of trailer to hold 'chocks' in place and then use the flexible bendible stuff to create pressure on the ply.
Thank you, guys,
A disposition to preserve, and an ability to improve, taken together, would be my standard of a statesman...
But what is liberty without wisdom, and without virtue? It is the greatest of all possible evils; for it is folly, vice, and madness, without tuition or restraint.
