Question:
what size power inverter can i use i think i can hook up two marine batterys under my bunk. thinking of fridge small micro tv and dvd....... thanks

Answer:
You better check with the company you plan on driving for before you start putting batteries under your bunk. Most companies I know wont let you put inverters (let alone batteries under your bunk) that large into a company truck. Most will let you get an inverter, but only of such a wattage that it can be powered off the accessary plug. (lighter).

Answer:
And those accessory plugs (cigiratte lighter outlet) only deliver about 10-amps --- about 300 continous ac watts max.
The appliances you mentined are all available in 12-volt configurations. Entertainment players and such are typically 12-volt models in big trucks. 12-volt regrigerators are also available (although very pricey) but exceed the accessory plug's limited power and require hard wiring to the truck's electrical system.
Again -- check this out with the truck's owner -- the company or whoever. There may be some strict rules on what you can and cannot wire, and for good reason. A truck's electrical system is dangerous to fool around with, and you can easily burn the damn thing to the ground if you just go in and wire it up yourself. Be careful.http://www.weather.gov/forecasts/graphical/sect...onusWeek.php#tabs

Answer:

Ferget the coffee maker. I went that route and only used it once. Itsa pain to clean after each use.(unless you have a sink in your truck)
Turned out the only thing it was good for was to heat water for instant coffee when I didnt stop near a T/S for the night ....Think about it and save yourself some $$$
