The WDH is a great option for travel trailers, but I don't know if that's a practical solution on a boat trailer. The weight/balance of the trailer changes dramatically when launching and recovering the boat, and I suspect that wouldn't work well with WDH bars attached. Obviously you can remove them before hitting the launch and then set them back up before towing home. That process would be annoying to me, especially after a long day on the lake.I'd consider a weight distribution hitch. This will transfer the weight of the hitch to the trailer and to the front of the Bronco a bit. I used one on a Chevy S10 when pulling a 24 foot bumper pull camper from Virginia to Florida and back. I wouldn't rely on air shocks, although as a kid I used air shocks a lot. Hindsight now I should have done weight distribution hitch to begin with. IMHO.
