Agreed Dave, I wasn't bashing your advice, or Ultrasport's by any means. A 3500 watt inverter is a big hungry one. I was just pointing out that it can be done if dialed in correctly. I actually think I'm pretty lucky. Several gurus on the tech forum over at Woodall's Open Roads Forum ( a really great place to get advice IMO) told me my (proposed) system would never work, but it has and better than I thought. I actually screwed up early on and let my batteries drop to about 10.5 on 2 separate occasions, but they're still kicking right along.
I think your advice for a smaller, stand alone fridge inverter is a good one. I had a cheap Cobra that worked very well for that before the Tripplite, but it was LOUD!

No I didn't take it that way at all Eric. You gave good solid advise. I used a single 220AH battery for a few years w/o too much trouble but tried to stay at 50% DOD on my AGM when possible. I even let it drop to 9.7v once and the battery came back fine. Wet cell batteries can drop to about 30-40% every now and then before charging and not do too much harm the batteries. Each type of system has its own pros and cons. Thats why this group is so good...lots of variety out there which can get complicated from time to time and discussion like this is proactive.
