Yeah I've been looking high and low, coming up empty handed. Everyone wants to sell me either a 30' long 14k car hauler or some pos that they wont even post pictures of the frame because they are in shame of their booger welded pile. So new is slowly looking better and better, but sadly out of budget.
As far as being maxed out it is something that I wont do. I plan on multiple 6 hour one way trips and eventually cross country trips, so I would like to avoid any problems. Also I would kick myself if my 10,000 dollar rig got totaled because I skimped on a sub par trailer.
