The Hefty Fab guard is just ok. It still leaves about 3 inches of the washer bottle assembly exposed from the front and does nothing about side contact. I attached a few straight on pics of mine to illicit my point. It seems that on the Hefty bumper it would be fairly easy to make a larger bolt on guard to resolve the situation. Maybe Chris would consider making one. (Chris says he's never hit his and neither have I, and to the best of my knowledge neither has anyone else, so maybe solving a problem that doesn't need solved?)
I believe that I saw a washer bottle kit that used the existing location but was smaller and didn't come down as far. Unfortunately, I can't seem to find it now. I'll keep looking. For myself I have it on my over the winter list to do something about it. But I have also decided against going to a 2 battery setup for a few reasons. First the issue with getting everything under the hood and protecting the washer bottle at the same time. Secondly, weight and cost. I haven't yet drawn my deep cell battery all the way down winching so I decided on 2 of these

One for jumping the other for general recharging. For me it seemed cheaper and easier to have these than all the work and cost to achieve the same end result. Especially on the recharging end of things with the kids endless use of electronics. Plus the Antigravity Power Supply does a better job recharging laptops than the truck has. As well the truck will recharge the power supply although it takes quite a while.
Just my poor mans solution to the problem. I may someday go to a two battery setup but for the time being...
