thanks everyone for your input. I made it to Florida safe and sound, the trip was great over 3 days. I did manage to get the fridge going on my house 400amp batteries ( charging with solar and a dc to dc 30amp charger running of the pickup)
As for the heat I warmed up the rv a few days before departure with space heaters. I kept the rv in the 40ies while on the road and with the app I brought the heat up to 30 min before taking a pit stop. We shut it down the next day for the rest of the trip since it was getting warmer and I did close the tanks.

thanks for all great info
