Wow! They are pricey. I think I would fabricate something myself with a standard hitch basket and a truck bed box made from aluminum. Or maybe even make or have someone make one completely from scratch with diamond plate and aluminum stock. Check out Tractor Supply Co. for baskets and boxes.
That they are. I was shocked myself to see the range of them. With the price of steel climbing quickly and aluminum has never been inexpensive plus it requires more skill to work with I'm guessing by the time I paid someone to design and build I wouldn't save much if anything. It likely would be heavier as well, even in aluminum. I don't need the box removable from the mount at all, wouldn't have anywhere to store it at the destination. Locking and weather resistant are key here, I don't want to have to deal with straps and the like to tether down a tool box or similar. Simplicity for wife and kids carries a lot of weight in the decision.
I'll check out some more YouTube reviews and come up with something soon, season is almost upon us. If I had to guess the Stowaway is where I'll end up, I just know whatever I buy I'm likely to have for years so I want to do my best to make the right choice.
@ManUpOrShutUp I agree on the rooftop carrier. Neither of us is tall, it's a struggle for me to get up w a polisher and reach the center of the roof without a ladder or standing on a seat which I'd prefer not to and I feel that would make dealing with loading/loading it that much harder.
