Gone are the days when there was a significant difference between full and midsize as far as width. Full size looks bigger but when you actually measure it's only a few inches difference. That said the midsize have shorter wheel bases which does help with being nimble and they're also shorter...
No issues on either of mine with the OEM battery and charging cable intact. That said, my last one was topped up by my solar set up all the time. Going to ditch my OEM one on the XD since I am getting ready to install a winch.
Santa Ana Wheel. It reads a few mph low. I did a bit more rougher offroading and did experience some minor rubbing when hitting woops while turning. Will need to investigate it a bit more.
