99F250 PSD CC SB electrical/aux battery questions

[Athabasca]

I finally have my F250 back in Canada. Great truck and it was a nice trip from Denver to Yukon towing a Conqueror Basecamp but thats for another thread I guess.

I have a it in the hangar now installing cold weather gear,a bypass filter and headunit/nav.

This thing is real short on real estate for adding any kind accessories. I wonder where folks are putting anything like accessory fuse boxes, aux batteries, etc?
My old STI had more room under the hood than this truck does.

Of course theres the bed but this winter its open to the weather and next it will have
a fuel tank back there.

Has anyone put a battery under the truck attached to the frame rail?

Open to any ideas now. Thanks for any replies.

I usually put a G31 battery box forward of the right wheel well in the truck bed. Nothing really goes there anyways. Then connect it to the main battery with a continuous duty relay. All my accesories get connected to the aux battery buss after the relay. So if I turn off the relay I don't have to worry about one of my accesories draining my main battery. Winch and Aux lights go on main battery, straight to the option holes in the car audio clamps. Computer, inverter, radio, smaller lights, seat heaters, etc. all go on the Aux battery buss.

No reason you couldn't mount the aux battery on a tray attached to the frame.

I generally use a Car Audio fuse block with a few outputs and 4g cable. I often hack off the main battery clamps and use car audio clamps with more terminals for ease of connections. I often just use a couple of copper bars mounted on isolators inside my cab. Then just drill a hole as needed to connect small accesory ring terminals. Easier and cheaper than a fancy distribution block.

What's the deal with the fuel tank? For farm equipment?

I live in the central Yukon so I always fill up when I am in town.The more the better. We also have some distances here beyond one tank of fuel. Maybe one day I will go part time WVO and use the tank in the bed for WVO.

I have found that the E350 vans have batteries on the frame in a nice enclosed box so maybe Ill go that route. I think the trucks share the same frame so there may be holes in the frame already for the box.
