The Power Wagon is available with the limited interior with the level 2 package (level 3 on 22 models). On the leaked Rebel build sheet it looked like the Rebel is an option package on the Power Wagon. As long as the Rebel, if it is announced, doesn't force you into a diesel, that would be an option to get the limited interior with a 6.4 hemi. I wouldn't be surprised if the Rebel package forces the diesel though.
I want a Power Wagon but need a higher tow rating (12k). However I don't tow heavy very often so I want the hemi. I think the Rebel, though it will likely lose some of the Power Wagon features, would be a good compromise. I'm patiently waiting on the October announcement before I decide what to order. If the Rebel forces the diesel I'll probably go Laramie but I'll also think hard about a Power Wagon and add some air bags. I know that adding air bags doesn't technically change the rating but I only care about actual capability.
