Xantrex 1000 W inverter on sale for $28 at Costco

[B_and_D]

Last time I went to Costco they had a Xantrex 1000 watt inverter on sale for $28. I didn't buy it then, but I did buy one tonight. Now I'm wondering what I can do with it. The manual says it can run a 600w microwave (that would be cool) but I'm not sure if it will run my laptop (or if it will damage it). I've thought about mounting it somewhere but where would it fit in our 2720? Ours is not the SL model so the batteries are on the tongue. We carry an auxiliary 12v battery that we move around to run the TV/DVD so we don't run the two 6v Trojan house batteries down. I'm thinking that we can attach the inverter to that battery.

I could probably put it under one of the dinette seats and install a 120V outlet somewhere down there that I can attach to the inverter somehow. The manual shows how to connect it with an inline fuse and cutoff switch. I believe that some of you have installed inverters and and am wondering how you've mounted them and what you use them for. I didn't see any instructions for grounding in the manual.

Over the winter I thought that the Trojans were starting to fail, but we just dry camped for 4 nights and they stayed mostly at 12.4 to 12.2 the whole time. We didn't use the lights much though, and our new fluorescent light over the dinette table helped a lot. They are getting a bit weaker but still holding out.
