I purchased my KZ 130RD specifically because it's 7'6" wide and I'm able to see fine without extensions. I can see the pretty common 8' wide trailers being a problem. I added a Bluetooth rear camera that really makes the towing experience even better.
I purchased magnetic under cabinet lighting that is motion and night sensor so that when it's dark and I open the tailgate, it lights the whole bed. It also acts as a hands free hand light if needed and charges by USB. Had it 2 yrs and works like charm. Hope this helps.

I ordered a '24, AWD, 4K eco, without the sunroof, but my dealer called me a month later that he had a "23 that was declined with the sunroof, factory mats, AWD, 4K, eco, and it was 2K cheaper than the "24, so I bought it and absolutely enjoy it.
