I get what you're saying. The nice thing is that if something goes wrong with the vu4 or Ecu, it's right there. 4 screw ad I have full access. I'd rather not be laying out in the rain or dirt on a shitty day when all it was was a plug came loose on the Ecu or a fitting on the vu4 wasn't all the way in.
And honestly, dirt isn't the real problem. The problem is people in alaska are fucking thieves and there's no alarm on my bed. I've literally seen people break out windows for avs switch boxes and even one case where a guy cut out a guys drivers rear wheel well trying to steal wheels. If someone wanted this stuff, they'd literally have to break into the truck, take my seats out and take the console all before my alarm woke me up.
As far as all the air line, if I had a back seat, if worry about it. But I don't, not will I. My truck isn't a taxi as everyone else thinks.
Ill have three lines in the cab vent on each side. One front, one rear, on both sides and then a fill on one side and exhaust on the other. I won't be tucking it in the carpet. How clean my back seat looks isn't as important as it is for me to have everything readily available.
What do you run on your truck now for airline?
