460 Ford engine stalls when put in gear

Thanks all y'all for your support, technical advice and good cheer. I've done nearly all my own car repairs for over 50 years and to say that these RV things are a challenge is an understatement! I'll check the engine ground cables and straps and hopefully when I get the shakedown problems shaken out of this thing I can do some quail hunting. For the next few days it's off in my Caravan to LA for Thanksgiving with my daughter.

BTW have a wonderful Thanksgiving everyone!!!

PS since I'll be in Tucson until April the gas treatment sounds like a great idea.
