I had factory vehicle and TPMS on my RV in the past and currently have the integrated system with my 2020 GMC. Both are very accurate compared to my tire pressure gauge and can easy see tire pressure variances while towing. You can see the difference in pressures based on sunshine and wind direction. Our main focus is tire pressure and temperature on our camper and have caught a potential tire failure as we had one tire fall several pounds below the tire on the same side. We were able to stop at the next town before the pressure got to low and we had a nail in the tire. If I didn't already have tire pressure sensors on my TV I would add sensors.

The RV fridge did great until ambient temperatures rose above the low to middle 90's and then it was a struggle to keep items cold in both the refrigerator and freezer even in the shade. Our fridge is in the slide which causes issues with air flow behind the fridge even though we installed additional cooling fans to improve air flow.

Our installation included a 10 CU FT fridge, 1500watt inverter, 30 amp transfer switch, power meter and 2-6 volt golf cart batteries. Both fridges fit through the door.

Most of our travels are at locations with full hookups in the summer and typically in the southern states and prefer to have more food storage, frozen ice cream, cold milk and everything kept below 40 degrees in the fridge and below 0 in the freezer. Since the modification we have been very pleased with the results and has met our expectations. No more ice milk for ice cream, no more fetching bags of ice, no more damaged food.
