Just keep in mind that a 2000WATT Power Inverter can pull between 160-180DC Amps from your battery bank when fully loaded. This will require HD cabling and more than one standard size batteries. You also want to not plan on using your standard truck alternator in a situation like this when charging... This is alot of DC Amps being drawn...
You also should follow good installation advice and NOT install the Power Inverter in the same location as the Wet Cell Battery bank. The batteries can emit explosive fumes when being charged and a small spark from DC switching action could set off an explosion... Probably never happen but it could...
Just saying....
