How long is that rig all together?

I can't remember for sure.... either 73' or78' is jumping out at me but I have had two different trailers, 2 different tow bars, 2 different trucks and 2 different 5th wheel hitches, and mounting positions in the current truck.I've been meaning to measure it again and been meaning to make a video next time I hook it all up and move.

I used 10 gauge wire and a 40 amp fuse but have warm wire and 1.75 volt drop at the compressor... My clamp meter shows a 29 amp draw... Guess I'll have to up it to 8 gauge

I did LOTS of wire cutting n crimping and built 95% of the wiring harness for the switch panel.. the heater mirrors are wired and functional. The mirror turn signals are wired and terminated under the steering column but I haven't figured out which wires to tap into yet.

I installed the 3 way valve under the dash and wired it to a temporary switch (all black in pic) till my dump switch arrives.
I also decided to mount the regulator under the dash and turned my 4 bank switch panel into a 6 bank.

I also took the whole air system back apart to seal everything with teflon.... The system is now completely plumbed except for my pressure switch that I HOPE will show up tomorrow..... At this point I can only find one small leak which is the temporary plug I put finger tight in the port where the pres switch goes...

Accidentally tested the pop off valve today too... I had the compressor running and got side tracked and didn't unplug it so it got above 150 psi... the pop off is set for 165 and it SCARED THE CRAP out of me when it went off.... It dropped the pressure in the 3.7 gallon tank from 165 to 80 in about half a second.....

I got my turn mirror signals wired up to the harness under the steering column and I also rewired the compressor with 8 ga wire... now I have a .25v drop instead of the 1.75 I had with the 10 ga. I had an extra starter relay so I mounted it on the fender right next to the existing one and wired the compressor from it... I will install a 50 amp fuse between the constant hot on the starter relay and the same on the added relay.
Now the compressor is drawing 33 amps and running faster plus the wire isn't getting hot any more.
I routed the remote air intake for the compressor and put the roll n lock back on.

Since I'm sooo good at staying on task I got distracted and removed the driver's seat to get the upholstery off to get a small tear repaired...... I MAY look into swapping the bottom covers and foam between the driver's and passenger's seats....would be like a whole new seat again.
