I would appreciate the info David. For everyone thank you very much for the information and thoughts. This will make it much less stressful to build my own system. If anyone else has additional thoughts please send them along.
Tracy, as a side note, if you ever wonder if the time and $$ is worth the annual trip to Oshkosh every year just to stand outside in the heat and rain - - it is. Because guys like me get to talk to guys like you. Thank you. You will also be surprised to know that MONEY is always an issue as you will realize when I have to set up a monthly pmt. schedule with you for the redrive / fuel pumps / EC2/EM2 :))
Thanks again,
Randy
