It's not bad a bad suggestion, though. The Power Wagon is more truck, is even better for off-roading if you're into it, better approach/departure angles, higher ground clearance, better suspension, can carry and tow more, etc. It also comes with more options like a winch, rear lockers, bigger Hemi, dual alternators, more color options, same body as the Rebel but the wheels and hood you want.
I bought the Rebel last year because it was fine for my needs and I really liked the look - there was no Power Wagon that looked like it. Ram's changing that this fall with the 2017 model. The prices between the two this spring were down to about $2k for similarly configured trucks. If that remains the same, I'll be seriously considering the Power Wagon myself to replace my Rebel down the road. It would certainly be worth my wait to see at this point.
All depends on what you want, of course. If you've read the forums much, you know that a lot of guys have concerns about some of the shortcomings of the Rebel as a 1500 series truck. Many have expressed the desire for the 6.4 Hemi, higher load/towing, rear lockers, and aftermarket items that just haven't been developed for the Rebel, like bumpers and winches. If any of that concerns you, you might thanks us later for the suggestion. Or not.
The downside is you get poorer gas mileage. The cost upside is the Power Wagon has a long track record of high resale/trade-in value. The Rebel will probably be the same, it's too soon to tell for sure, but Rams do well regardless.
