For a small fridge micro and heater, will an inverter work? Just trying to get prices set my van up. Looked at floors and e-trac most of the night. My brain hurts.

yes.

......everything has been discussed before. it is possible to find them when you use the search/advanced search and type in ..inverter.

if your gonna run a small fridge gonna need a small battery bank. You defiantly dont want it running off your starting battery. Also a heater wont run off battery's unless you had a ton of them.

I am gonna put a 3000 watt peak inverter in my van I got one from harbor freight for $110 with tax yesterday. I am gonna run it off of a deep cycle battery and let it charge as I drive with a switch between the deep cycle and the engines battery.

I think my idea will work I will run a positive wire back to my deep cycle in the cube, with a switch inline, run 2 heavy wires to inverter, and then ground through a hole i will drill down under the cube.

anyone think my idea will work ?

As Jack said, if you search, you'll find that [as Chris said] Turtle is indeed the go to guy, and he's written several exhaustive [I didn't say exhausting, lol] posts on the subject. Seek, and ye shall find. :)

You gonna run an 8" Makita and a microwave at the same time? :D

Make sure you fuse it right before it hits the battery. A good ANL can be used, a Class-T is preferred. Use thicker wire than might be indicated for the current load, to minimize the voltage drop that occurs for longer cables. 10 feet of cable can be as much as half a volt drop, depending on the size cable that's used. If the alternator is putting out 13.5 volts and .5 of that is lost in the cable, then only 13 volts are gonna get to the bank, which won't charge it.

with a switch inline,
Should be a battery isolator, or a battery separator if your alternator doesn't get along with and play well with isolators. A simple switch will get you into trouble because you will forget to switch it, thereby running the cranking battery down. Get an isolator by Sure Power or Hеllroaring.

run 2 heavy wires to inverter,
Again, fuse the positive cable right before it connects to the battery.

If you're going to run any other 12-volt loads off the batteries (Espar, roof vent fan, Igloo cooler or other 12-volt appliances), you should consider a busbar for those connections, rather than a snotload of 12-volt connections to the battery terminals.

and then ground through a hole i will drill down under the cube.
You don't need to go all the way down to the ground. You can just ground it on the chassis. :D

Sure. If you know a local RV repair guy, might want to run the installation details by him, as well.
