The receiver mount is a terrific idea, and I'm definitely interested in it. Please note that I didn't say "all" options were massively protruding. What I said was "Most of the options I see are in one of two groups", which includes stealth and massively protruding, such as the EXO Winch Mount. Since that style of mount is fixed, it could impact the approach angle, just as your setup would if you left it on there. Of course a removable solution is not going to affect approach angles, since it is not on there until you need it. An accessory that is not in place is obviously not going to affect geometry. I'm mostly looking for a fixed installation that allows spool access without sticking out 12" in front of the truck down low, which, with basic geometry, could affect the approach angle. I find it interesting that most of these types of products do not include a direct side profile view in the marketing materials. I wonder why that is.
I have considered the hitch mount, and I like the idea. In fact, I already saw your thread about the project, and it took quite an effort for you to get this front hitch mount system going, and it required fabrication. I would much prefer a vendor solution, if available.
Ideally, I would like a front integrated bumper or lower profile mount system that still allows winch spool access, something which other truck platforms have in abundance from an array of vendors. It seems that the Silverado in general, and particularly the Trail Boss, have limited support from the marketplace in general. 99% of the fixed mount solutions are in one of two groups: 100% stealth, with no spool access and limited spool visibility, or they stick out like this EXO kit shown below does. Since there are no side profile views available, it's hard to say if this affects approach angle or not. I just want to be able to mount a new bumper with a winch platform in it, that actually allows me to see the spool, and not just by peeking through the fairlead.
Also, with a hitch mount, I would love the convenience of it, and the ability to winch from the rear receiver. I would also be concerned about torsion forces concentrated in the front center of the frame if a front pull had to go sideways, since the load will be concentrated in the center of that frame member, and not spread out as wide as if it was using bumper mounts on the frame. Thoughts?
