Being a "handyman" - of sorts, when I go to the summer cottage or to see the grandkids, I need to have my tools and their accessories with me. Rusty, my faithful hound takes up the cargo area of the SUV, so I needed weather-resistant containers.  I have a trailer-hitch carrier which readily accommodates these containers- on either side of the license plate - and allows the tailgate to open while they are still on the carrier. Perfect.
