I've been running the SB70 for a while now, with the stock battery (79ah) and a 120 watt solar setup and love it. The fridge runs incredibly well, and super efficient. It does tend to vibrate so ensure you mount it nicely and buffer it a bit if possible. It makes ice on level 3! What more could you ask for (more room I guess - but it's fine for the 2 of us).
Looks great.
Glad to hear you like your fridge! I can't wait to really get out and test mine, but it held at 38* all weekend no problem! Thanks for the compliment!
