i've added a few things... thought I'd share.
PMF three links.. got my castor back!!!! super easy install, top shelf quality product- followed the instructions to a 1/16" (PMF called for a 32nd) and didn't need an alignment- it was balls on using the GPS and laser rack the next morning.
went back to 20's- and ran STT Pro's prior to this pic.. dropped them and sold 'em, loaded up some ProComp AT Sports that I'm super happy with. my range went back to around 1800 miles with these tires, when the STT Pro's dropped it to around 1400miles... if I had to choose just one tire brand/model for the rest of my life it would be the STT Pro's, but economy on the long haul i pull a few times a year forced me to an AT tire...
got her nice and salt painted up in the north country over the Holidays- drove 1472 miles in 22.5 hours in the middle of that storm everyone was talking about. it was.... interesting, and the procomps handled it fine.
slapped a group 27 AGM bank in the back, fed both by solar and engine generated power and protected via this isolator- 500a constant 950a peak... ran 2ga wire back to the box to manage charging from the alternator.
and then there is this... I found them so cheap i bought two- one to use, one to sell to recover costs.
i pointed placed the exhaust on the frame rail opposite the airdog lift pump, which in theory will reflect heat to the spin-on's and guard against gelling (not that I've ever had an issue with that).
and to complete the thought process on the eberspacher, and with the dogs health and comfort in mind (or if I'm forced to sleep with them), I installed a heater core in the bed and a permanent boot between the cap and cap:
the eberspacher has already paid for itself so far as I'm concerned- and it was mighty nice to get into a truck with frost free windows and at least 50* when the ambient temperature was well below zero... I put an inkbird thermostatic controller in the bed and set it up to turn on the heater core fans when the heater core enclosure gets to 90*, as well as fire a dual headed fan I mounted in the bed/cab pass-through... I've got it set to turn on above 110* too, with a hysteresis of 5* and a temperature achieved time of five minutes for summer.
oh.... and I put 5100 bilsteins on the back and 5160's up front, along with billy dual stabilizers (pending, I've been running a RC dual system but the cold had it's way with them).
people can talk all the trash they want to about these 6.4's, but mine is solid as any truck I've ever owned. and this one is set up right for the long haul. I'll keep y'all posted if there is any interest.
