During my travel trailer days we went through a spate of tire problems and blow-outs. So, now that we've got the 3051S I figure I need to keep on top of any tire issues. And proper inflation is number one.
I haven't purchased a TPMS... yet, but probably will.
But I did order one of these super rugged RV specific Viair Air Compressors.
Man, I'm super impressed with the product. Rugged and well accessorized. It's better than my big "home" air compressor system.
If you haven't seen one you should take a look - really good kit:
