Nice job Trailbus , sorry I did not make it to the meeting, but what you have done is perfect you have solved all my questions. THANK YOU

It was all pretty easy. Tearing the stuff out of the engine bay corner was straight forward and obvious (as was cutting the OEM smog pump valve bracket.) The hard part for me was trying to figure out where to put the Smog Pump valve. I was going to put it on the innerfender till a friend pointed out those 2 bolts. I used the OEM hoses by cutting three 90* bends off of them. The hose going to the pump is 2 pieces spliced together with a 1" piece of 3/4" ID copper tubing. I looked around for a new piece of 7/8 ID rubber hose but it's not a very popular size. Plumb the valve in first and make a bracket to hold it up. It was pretty solid with just the hose (I ran it that way a couple of days). I just didn't want to risk stressing anything.

All together I spent less the $60 on the tray project (I had an old battery laying around).

That is awesome.. you should do a write up on it step by step install type thing... !!! I am going to attempt to do this job pretty soon.. What did you use for management in terms of charging both batteries, do you have a solenoid install or are they both wired to one another?? is one on stand by all the time and you flip the switch, or is one your accessories battery and the other your main start up battery?>??

Just another observation here.....

- the original poster has only space for a battery
- material cost for a second deep cycle battery, wires, terms, batt management system
- some labor time

OR

Get one of these and be done with it.....

Sure this thing is heavy but not much more than two full size batteries...
Sure this thing is expensive but add up the cost of what I mentioned earlier
You STILL get better performance than any two Yellow Tops
Sure this thing is big but you can make it fit

I just hooked the 2 batteries together and ran a second lead from the alternator to the second battery.

No redundancy, all your electrons no matter how many you have still are in one basket.

You know, this thread took a very unexpected but *very* interesting turn. Is anyone actually doing this?
