Glad to hear you have it set up so it's safe. Much easier to tow when level. Sounds like you have it set up really nice. Yeah, it's long, but when articulated, it's amazing how tight of a space you can get into, and out of.
I also like that you have a travel vehicle after dropping the trailer. Hmmm, got me thinking...no, stop thinking. That's what got me where I am now! ha.
Good luck with the school bus project!
