I'm looking for a solar panel combiner box for the RV's roof. I'm going to start with 2 panels with the option to add 2 more if needed. I've seen some that are stupid expensive and some that aren'...

We're completely off topic from my original question about combiner boxes, however, that's not always a bad thing.
Time2roll - Not questioning you, just asking ... how do you know the panels have bypass diodes? I don't see it in the spec sheet. If they do, then wiring in series would be acceptable for my set up? As in, series would be virtually the same as parallel using smaller 12v panels?
red31 - your data shows a 20' run. That's the distance from the pv panels to the CC right? As in, they are 20' apart, not 10 feet.
Using MC4 10 guage extension wire gives a ~ 0.38V drop at 20' ... and this is OK? So using 8 gauge extension wire would be even better at ~ 0.23V drop at 20' ... right?
