I installed an inverter, but still have my ammonia absorption fridge.
I too had considered the Tripp Lite... I know the brand well from the information technology industry.
A few things I didn't like about the tripp lite was lack of rv specific features; especially low battery voltage cut out. it will suck your batteries all the way to 0 if you let it. more expensive inverters like xantrex and magnum have protection against that sort of thing.
the charger is also a bit weak in the tripp lite. if you're getting a 2000 watt+ inverter, you need 600+ amp-hours of battery bank, and with that much battery, you want a 100+ amp charger... like the Magnum's 125A 4-stage charger.
as to how to wire it, instructions are provided in the installation manual. I can help with specific questions if you like.
many folks recommend just wiring the inverter to the batteries, and plugging your rv's power cord into the inverter. I went a step further and utilized the transfer switch built into my magnum. the power cord for the rv (shore power) connects to the magnum's input, and then the magnum is connected to the breaker panel where the rv power cord was connected before.
I like 12v batteries myself, big group 31 agm to be specific. lots of folks prefer 6v golf-cart batteries. it all depends how much space you have, how many batteries can you fit in there? if I had all the space of a huge motor home, I'd go with 2 volt "jars" instead of 6 or 12v batteries... the jars are designed for massive current and very long life, compared to 6 or 12v batteries.
6 or 12, you'll want at least 4 batteries to have enough amps to satisfy that inverter... do you have that much room?
