I have a 100 watt Renogy solar panel that I love.  They run about $140 on Amazon right now.  I actually have a thread in this section on how to connect to the Zamp port on your Pod with such a panel.  It's not difficult, and I have step-by-step photos.

Everything I've heard about these panels has been positive.  They're high quality.

Yes I did.  The Renogy charge controllers are alright, but SunForce is recognized as one of the best of the small charge controllers out there.  For just one 100 watt panel, a 10 amp charge controller is fine.  Adding more than one 100 watt panel can get cumbersome due to space, but really it's all that most people really need considering that you're just powering lights, your water pump, and other small things.  When you're dry camping, you'll obviously be running your fridge on propane.

I would expect that most all solar panels are workable products. I wouldn't recommend the amorphous type, the polycrystalline are more long lasting. In my opinion getting the more expensive maximum power point tracking controller is worth the extra money in the long run. You'll harvest more energy than with the cheaper pulse width modulation types. Yeah, solar energy is expensive. But after spending good money on a high powered panel, why limit its output by going with the PWM controller. Just my two cents. Other users are quite satisfied with the PWM controllers.

By the way I too just purchased my Rpod (2016 171, in Coos Bay, May 2016). Our Rpod is equipped with a 36 volt, 185 Watt Shuco panel. It uses a http://www.morningstarcorp.com/products/sunsaver-mppt/ - Morningstar SSMPPT-15L max. power point tracking controller. They run about $200. This controller harvests maximum output and converts voltage down for 12 volt battery charging. If you would like to see my setup, send a private message for contact information.

Welcome to the forum! It is a gold mine of useful information   

There's no doubt that MPPT controllers are superior to PWM controllers.

That being said, the cost differential between the two is substantial, and you'll have to be using your solar panels quite a lot in order to see a substantial practical difference between the two.

I believe that for no more than 100 watts of solar panels that a PWM controller is the best overall value for the money.  For anything larger than that, it's probably worthwhile to get an MPPT controller.  I just don't see many people having more than 100 watts of solar panels with a rig as small as an Rpod.
