Correction on my part.

1. I ended up buying a Chameleon 29er instead of the 27.5+ that I had asked about earlier. For the riding I do, a 2.25-2.5 inch tire is more than adequate.

2. I think I overstated the weight on the rear rack. Just did a 3 dayer on my existing bike using a front bag, back pack and trunk bag with built in panniers. Total weight added to bike was less than 30 lbs.

Does this change anything?
