Why not just use a Battery Isolator ?

I have one from painless wiring. Works good. Has a switch in the cab to choose which battery you want, and crosses the ameprage when in dual batt. mode. I love it. Works good in winter when it;s hard to crank. You also will have a good battery if you leave your lights on. I think everyone should have duals. One of the best investments I ever made.

How much are those isolators? I have been running dual batteries for years. They have made sure that even at -30 degrees outside my truck always started but they were always open for both to be drained at once. I would like to have one as a true back-up now that I am in a less severe climate. Yes you do hook them in parallel, but if it is really cold and you can't get it started just momentarily jump them to series on start-up it your truck will definitely start!!(not advised unless absolutely nessasary!)

400m,
I'm going to be running dual "house" batteries (to power 110 items through an inverter) in my 82 E-150 in addition to my vehicle starting battery and plan on using an isolator. Having an isolator allows one to use the extra battery without draining the vehicle's starting battery while still allowing all to be charged by the alternator.
Prices range from $21.95 all the way up to $119.95, depending on your alternator and number of batteries.
Click the links below for two pages with isolators:

Here are the correct links to the isolator pages, which should work fine:

Sorry 'bout that - not used to doing html the way this forum needs.
Let me know if you want links to inverters or other electrical needs.

One more time (this system seems to have maybe added a link to motorhaven.com to the html for JCWhitney in the previous post).
Here's the URL for Whitney's isolator page:

400m,
Here's a good link or two to a great place for alternators and parts, with pages just for Fords. They answer queries and tech questions pretty fast, too.
Extreme Duty Alternators for Fords:
[link:www.alternatorparts.com/Ford_3G.htm|http://www.alternatorparts.com/Ford_3G.htm]
Alternator Upgrade kits:
[a href="http://www.alternatorparts.com/ford_alt_repair_upgrade_kits.htm"]http://www.alternatorparts.com/ford_alt_repair_upgrade_kits.htm[/a]
It is my understanding that if you add a single battery and do a fair bit of distance driving (which will charge both batteries sufficiently) you might not have to upgrade your alternator. If you use your vehicle only sporadically, then getting a bigger output alternator will definitely help.
Eventually I'll have a 160 amp alternator with dual house batteries (and appropriate isolator) and a 1500watt inverter.
Later,
Sherman82
