I have a Ez Loader trailer (tandem) with a 190 Sea Ray boat. The trailer has surge brakes, there is a "lever" on the tongue which is labeled "reverse". Which I am sure just frees the wheel. My question (or concern) is launching the boat, I have a Nissan Frontier V6 2wd. A steep ramp which is usually wet, I am afraid I may go swimming sooner than I hoped too! Any thoughts?
