I'm looking to upgrade my trailer. Have a local Shoreland'r supplier and I'm impressed with their sales support. We looked at a few options for my 2800# dry weight 19ft boat. I've vouched for a tandem 4000# trailer even though it's more coin. Any feedback on their product. Does a tandem take away more road shock? Also, I'm leaning towards bunk verses my current roller set up. I struggle to center this thing everytime. Any feedback would be great. Seems like prices are a bit more here since the tandem runs $3500 plus good old Canadian tax!
