Nice looking trailer. Is it extra tall? Good call on the axles - way too easy to overload a pair of 3500lb axles with a big trailer. Eric is "smarter than your average bear."
Your tire pictures reminded me of my last road trip. I shredded a tire on the LF of may van last month on the way back from Imperial Invasion. Tore up my inner fender, too. Not nearly as bad as yours.
The LR floor is dented from a similar flat on the rear a couple of years ago.
Glad you're safe and happy. I enjoy this thread.
