I have a 27.5 that I've put in the bed. It seemed to work fine but not ideal as it was still able to move around a bit. Just got a hitch rack that I'll use next time. The Kuat NV 2.0 seems like a solid option, being easy to get bikes on/off and won't mess too much with range.
10k since delivery in late Aug. Road trips to LA, Santa Barbara, and San Luis Obispo. Add the fact that I always now volunteer to drive everywhere bc my truck is flat out amazing. Every day I seem to like it even more.
Got a permit to get a tree in Tahoe and found a 16 ft tree that would fit just perfect. Looked even better when I put the lights on while it was still in the truck!
