Dear redwing2
I just purchased a 2010 28BHS and towed it home 550 miles in several snow squals and 20 MPH+ winds. I purchased the E2 weight dist hitch from equilizer. I had no problems with keeping the trailer on the road and the swaying was very minimal. once I reached PA the wind dead down and The trailer pulled fine. I believe the E2 and E4 hitch differance is due to the total weight being pulled. My 1/2 conversion van pulled everything just fine. I hope this helped you out.
