You might want to consider a Tire Pressure Monitor system. Sure takes out the guess work & kneeling down & fiddling with a tire pressure gauge every time. I had a tire pressure equalizer system on our 2002 Shasta Sprite, but decided to go with a full TPM system on our "new" Jamboree. I installed the system from EEZ RV Products & love it! I switch in on about 5 minutes before we plan to take off, it warms up, reads all of the pressures for me while I'm doing other stuff. No getting down on my hands & knees & fighting with the inside tires & all.
Worth the cost in my book.
