Plug them both in, but put a timer on each. Let one run for an hour, then let the other run. You'll be good enuff on both if they alternate back and forth.

Hey..... thats not a bad idea at all!
That way, I can tell my boss that:
"Sorry Boss, it'll be another hour before I can get to work"

I like it!

I think an hour off is too long in a colder climate....might work in Texas but in snowy Sparks Nevada I would think it will not get the job done.

You're probably right.
However, the alternative would be to show up an hour early.

I like the extra hour of sleep option better.

If you do go with the "put in another circuit / outlet" route, here are a few specs and ideas for you:

10-2 is good for 30 amps
12-2 is good for 20
14-2 is good for 15 amps

Your best bet would be an additional circuit ran with 10-2 to an outdoor/weather-tight 2 gang fixture with a pair of 20 amp GFCI outlets. The single 10-2 would need to be split to power the outlets individually, then plug one truck into each GFCI. I bet you could wire the controller Lary mentioned into the feed line to the outlet box (mounted to the outside of the garage) and turn the whole arrangement on and off on temperature.

Best of luck.

Nah you need a 1500 watt wind turbine. Then you could charge your batteries while the timer is off.

Or.......you could do as my Father would have done and just wake one of your boys up an hour earlier and make them go start the trucks and clean the snow off them before he has his bowl of oatmeal

So, a co-worker of mine let me borrow his tester and I tested the draw from both trucks last night.
The '06 pulled 660 Watts at 6.5 amps.
The '95 pulled 758 Watts at 6.6 amps.

Not sure why the difference, but it doesn't really matter. The combined draw ~1400 Watts is more than I'm going to put through said extension cord.
I've sent an email off to the rental management company to see if they'd be willing to let me "Have and electrician wire up another circuit in the garage" (Wink-Wink).

If yer going to run 2 circuits, use a 240V breaker, 12/3 feed 240V with neutral, then split it into two 110V circuits at the outlets.

Modern wiring code might require you to use arc fault interupters, which could be the deal breaker

These save power very good as long as they aren't installed under the hood> http://www.smarthome.com/7143/Thermo...Degrees/p.aspx

They are also available with different temp settings than the one in the link.

Maybe you could get Gilligan to pedal a palm tree bike generator that the professor built real fast.

Perhaps I could employee both strategies and get my kids up early enough to pedal the "Gillgan Generator" before I go to work.
(They need the exercise anyway)
