Yes, mine is the double cab. The brakes on my first one were a little touchy at first but I can't say that the brakes were totally to blame. I haven't had any issues with my current Tacoma so I'm inclined to believe a large part of the problem was me adjusting from driving an SUV.
As you previously stated, Tacoma's are workhorses. I've had 8 large bags of mulch and 12 landscape timbers in the bed of mine at one time. If the suspension can't handle the load in the bed, I guarantee it can handle it with a trailer. I accessorized mine so it doesn't look like just a workhorse. The accessories give it a clean, sporty look when it's not meeting the challenge of a heavy task. It's a badass in disguise.
I looked at various small SUV's and other trucks before I bought another Tacoma and, aside from the fact that I knew firsthand that they're solid trucks, a big deciding factor was also one of the reasons I got rid of my Tahoe - you're limited on the height of things you can transport (not to mention it was a gas guzzler). I say indulge your inner kid-boy glee! I'd be really surprised if you were disappointed.
Oh, and another bonus, Toyota's across the board hold their value, so be prepared to spend a decent chunk of change, even on a used one. Holding their value is the other bonus, not the large chunk of change. Although it's money well spent, in my opinion.
