When a truck driver is setting up a dc to ac power inverter in his truck he will need to make sure to cover a small checklist to select the right inverter size and where to connect his ac power supply. Once you take care of what and where you will be ready to head over to the inverter store and chose the right unit for you system. If you have small cabin truck you will probably what to go with a 2000 watt power invertor, if you have a large cabin truck like the one in the image below you might want to consider a larger unit that will give you a larger range of functionality. Because if the extra space and convert you might want to connect more equipment for a closer ambiance of home.
As far as where to setup the inverter, using trucks will have a compartment for this type of equipment. Usually within 6 feet of the battery. If the truck does not have a designated area to install your power inverter then you will want to install it as close to the direct current as possible, hopefully within 3 to 6 feet. If you install further then that you might start to lose efficiency from the inverter and you wont be able to use the full listed continuous wattage of the AC supply.
