They also make a plug that goes in the OBDII port.

It's not as convenient for regular frequent repeated use as a jack on the outside. If you are going to want to plug in regularly, then it's definitely worth installing a jack.

But if ity's only going to be occasionally, you don't have to install enything under the hood or touch the battery or anything.

Another thing is it allows to keep the charger and the end of the lead cord out of the rain inside the cabin in case the truck is not parked inside a garage.

You just need to find the best place to run a lead cord outside through a closed door without making a spot that leaks or pinching the cord.

I like the plug-in attachment. I did not know they had that accessory. Very tidy setup.

I have the battery tender cable connected direct to the battery terminals (it has an in-line fuse). The cable protrudes on the passenger side, top of fender under the hood lip. Its fairly hidden, cable ties in place. My tender is on the wall near this location so its an easy plug-in. Also, you can see it clearly reducing chances of driving off while still attached (done that a few times in other vehicles).

As for using the tender, if I drive every day, I don't bother. If I am parked or plan to be for more than 2 days without use, I plug it it. I have used these devices for 20+ years on all vehicles, ATV's and motorcycles. My truck sits for a months at times and it has two large batteries. I get 6-7 year use from these cells.

I understand that keeping the battery on a tender maintains the chemistry and may result in longer battery fife. Your experience may differ but I tend to get long battery life.

brumey,
How is your set-up working out at higher speeds? Does the exposed part of plug-in attachment flap around at all? How distracting is it while driving (visually or/and any noise)? Is it visible from the driver's seat while driving (although I suppose you try to tuck it behind the hood panel)?
