alt Hacker NewsI have a hitch for my current truck and honestly a dump trailer wouldn't be a bad idea anyway for some use cases, but even if I had one I'd probably only use it when I had to. The convenience factor just being able to hop in and drive, or having the truck bed with you when you didn't plan on moving something just wins out.
I think the conveniences are still tradeoffs though. A separate vehicle is handy for being able to slowly collect things to get rid of in one later trip, or to store something you just got until you're ready to put it somewhere else (I've currently got what remains of a 1/2 yard of sand sitting in mine). And being able to just dump something and drive away is quite nice (especially when you've put it into the trailer using equipment to begin with).
On the other hand, I've never experienced being able to just haul something without a little planning first, so I don't miss it.
