Do I need a weight distributing hitch?

I would look around at what the WD hitch manufacturers recommend. Everything I've read indicates the WDH is for heavier trailers with a tongue weight of at least 600#. This is about 10% of the gross trailer weight, so that would be just over 300# for your trailer. Our TT is 3500# gross and we tow with an Envoy. I asked about the WDH from the RV dealer and they said I didn't need it, just go for the sway bar. The first trip we took felt a little bouncy, but the Envoy has a real soft suspension. I installed Bilstein heavy duty shocks and the problem was solved. Is it bounce free? No, but 99% of the time it is.
