I don't see you need a dual battery either. They are nice to have, but I don't think needed for your application.
Cappy - you own stock in that company? Sure its a good Dual battery setup, but everything you said it can do the other systems do as well. That price seems pretty high even for a kit. Have you posted your setup in the FAQ thread on Dual Batteries. There you show your installed system and why yoyu selected yours and then the reader can review yours along with others to make a decision.
Nope, I havn't installed it in the 80 yet. Write-ups / FAQ stuff was gonna wait until I do my ROTW write-up. I suggested it due to my past experience, but I will refrain from making specific vendor suggestions if it's an issue. Sorry
