I use a single 235W panel and a Morningstar MPPT-15 controller. The controller puts me at just about the maximum for that module. If you are just going to use the two modules on an intermittent basis, there are less expensive PMW controllers that will work just as well. The nice thing about the Morningstar controller is that it is fully programmable through the software interface and has temp compensation functionality. I would look for those two features no matter which type or brand of controller chosen.
Tip: before you embark on a portable system, I'd suggest to take a module in hand and try positioning it. They are not that heavy but are larger in dimension than some anticipate. I wouldn't want to schlep one in and out of my trailer, let alone two. It may behoove you to mount one and then have a good connection system to a portable. That will give you some more option and functionality. When you are driving, at least a single module will be charging. The same would be true for storage.
