I am looking to replace my boat trailer in the near future. I have had a roller trailer for the past 17 years. I am not sure if I  should switch to a bunk or stay roller? I am by myself in the boat (17 foot boat) and have a tough time getting the boat back on the trailer sometimes so just trying to find out which one might be easier? The other question is trailer brands any specific brand easier than the other or better? Thanks
