Your Lund may be different, but I had a stratos and my current ranger both needed the front strap eye on the bow adjusted out further so there is enough room to attach the winch strap. I also had to switch the winch strap to pull from the bottom rather than over the top, or the bow would bounce on the trailer pulling down the road. Two things I will also say with the stratos on the bunk trailer once I was up close enough to power load to attach I had to make sure the motor was trimmed down enough or a couple of times the bow was light enough to lift up and over the drotto. I did it twice and that was a PITA to get the front back over the drotto to try again to latch. With the motor trimmed down it wasn’t an issue. The ranger bow is heavy enough it isn’t an issue. The Lund may be completely different. I actually have enough room to attach the strap and the safety chain. That may be overkill, but since there is room I put it on too.
100% solid advise on the bow rise. I bought a used boat with it on the trailer and I hated it for the first trip with it. Finally the last day of the trip there was a friendly guy at the ramp and gave me some pointers on loading with it… Keep trailer out of water just bit more than I was before, and keep the bow down.
