There have been lots of good comments. I personally wouldn't camp without a toy hauler. But my family comes with me most of the time and just being able to back up to the garage and load everything from the back ramp is so nice. I just lower it and we all walk the food, clothes, whatever in there. We camp often without our toys and still use the features of a toy hauler.
That being said, your use is a little different. If you have money just laying around and need something to spend it on, then sure, buy one. Outside of that, I'd keep what you got. Honestly, if my family didn't camp with me, I'd have a totally different setup.
