the Cat NRR40 weight is approximately 3600lbs roughly (without the battery).
So if your battery is 2k lbs then your total truck weight with the battery would be 5600lbs roughly.
I hope your using a low boy trailer, a standard trailer will make the OAH too high. Max height for any vehicle is 14ft i believe.
Just FYI, usually when these units are hauled they are laid down, the hyd tank breather is sealed off, drive unit breather capped so no fluid will leak out on the ground. You can haul it upright but like i said, height is the key factor so usually a lowboy trailer is used.
