A friend let me borrow his bob trailer last week for a 4th thing I had planned. I have been seriously thinking about getting one for a while now. I put the skewer on my single speed thurs night and took it for a test ride. Then a few times Friday including a trip to the grocery store. Which would be my main reason for wanting one. I would hardly have to drive at all if I could haul. Hauling groceries is 90% of my driving.
It is different, but not as bad as I thought it would be. It follows really nice and you kind of forget it is there. It has a lateral (?) stiffness that keeps you from rocking side to side when crushing the pedals. You also get the roller coaster effect of pulling it or having it push you on hills. Momentum is what it is all about. It takes a bit to get going, but once going it keeps going.
I get to keep it for a bit longer and am really gonna put it to the test. Thing is a bit of a pain to get in and out of the house. Ideally I will be able to keep it in my garage and hook up from there. I doubt I would go with the really fancy one with the shock since I would mostly use it on pavement. A bit of an investment too. But if it helps me drive less and gets me out on my bike more it will all be worth it.
