That's an M100. The grab handles, parking brake handle and lack of blackout switch are dead giveaways. That's an awsome deal for that trailer. Looks like it might have the original data plates under all that paint too! Enjoy it!
So today I started scraping some of the paint off to see how many layers I had. The white paint is what was put on it maybe 10 years ago. Original was green. But I found this: I hope I can find some replica decals.
