New Borgeson aftermarket steering box and shaft. check.
New upper and lower ball joints. Check.
Exhaust brake installed. Check.
I would not tow heavy without an exhaust brake. I like the fact that I can come down a moderate grade at 60 in 3rd and not touch the brakes, so if some bonehead decides to make my day they are nice and new and cool. Oh yeah, all the brakes are new.
I took out the two group 27 batteries from under the hood and installed a single group 4DM (marine deep cycle/starting) battery in the bed area. It is not lighter, but it is no longer corroding everything in sight and adding weight to the already loaded front axle.
The box is more of the epoxy and glass and 3/8" marine plywood construction. I vented it with large holes using regular window screen. It is plastic and will not corrode. I'm not wanting to find a hornet's nest in the battery box.
