Anybody ever connect an external battery?

The Lancer 880 only has room for one battery. I'm thinking of connecting a second one and using jumper cables to the main battery. Has anybody ever done this?

Jumper cables would be a poor choice . the battery/s cables should have a solid connection , wing nuts or bolted clamps . Many have added extra batteries secured in front or behind the wheel wells in the truck bed . Remember to cover the cable ends if the extra battery is not being used , they will be live if still connected to the camper battery .

I've looked at that Torklift box, but I think my installation will be more humble to begin with. Probably just in a std battery box and shoved under the truck when camping to begin. I may a cut ally install the box on my running board at some point. I have enough room there.

I'm trying to keep the cost moderate and that Torklift box is about $175 shipped. That's 2x the cost of a group 27 at Costco.

X2 on Torklift - manufactures very solid products.

Yes, and Torklift makes a holder for one as well. Take a look here. http://www.torklift.com/index.php/products/auxiliary-battery-storage/hiddenpower
