I probably wouldn't have paid it any mind if I hadn't winched my boat up short a few times, then noticed the boat nodding up/down on the road. I've even taken to finding a down sloping parking lot and slamming on the brakes to scoot the boat forward that last inch or two, then tightening down all the straps. It's much easier to do while the trailer skid carpets are wet. Trying to winch it down tight on dry carpet or on a level plane just puts too much pressure on the strap hook, as well as the bow eye it's connected to.
I thought I recognized the back end of a Blazer (I've had two of them in the past) ... but, I'm currently pulling my rig with a 06 Tundra, which doesn't have a very sharp turning radius. I could have almost turned my Blazers around on a 2 lane street, but I'd be up in people's yards if I tried that with the Tundra ... and living in an apt complex and parking my boat in a parking space can be tedious at times, which is why I usually just unhook it and push it into its parking slot. My concern with the step coming into contact with the vehicle is more focused on some narrow or short ramps, where you're supposed to pull down onto the upper part of the ramp and turn around to back down & launch the boat.
I do like the idea of welding it to the trailer frame, too. Not so much for being able to hold my weight, but to insure that no opportunistic thief could unbolt it and carry it off (considering their prices are in the $300-$600 range).
