Reply to a couple of other posts. I use CO2 instead of nitrogen because its cheaper to refill and my local nitrogen supply only swaps tanks. I wound like to keep the tank I bought. In some applications I think nitrogen maybe a better option, but CO2 works well for me. I also use the CO2 to run some air tools, etc.
Why do I check my tires every morning when I have a TPMS doing this job? I use a good quality digital pressure gauge accurate to +/- 0.5 PSI, the TPMS runs about +/- 2 PSI. I like to start out the day knowing what the pressure is and if a tire needs to be topped off its much easier in the campground opposed somewhere down the road.
I figure if a problem has at least one solution, then there are likely multiple workable solutions. I have have a tire solution that I'm comfortable with and works well for me and my equipment and use style. There are so many different RVs out there, variations in loading and use patterns I don't believe there is one best solution. Readers in this thread have raised many great questions and solutions.
