I have to laugh at those that carry the equivalent of a second kitchen sink, 40,000 miles in the last 4 years and not needed air yet.
If I did this is why I have a roadside assistance company (Coach Net)
I laugh at posts like this.
Let's see:
Option I-Fire up the engine, build pressure, connect to the on-board fitting and top-off the tires when the system pressure exceeds the psi required for the load on the tires. All the folks around you at the CG are just delighted that you are running the big diesel. Each time your system pressure is < your inflation pressure you smile at your neighbors, shrug your shoulders and wait until the pressure builds for you to continue inflating your tire(s).
Option II- Call Coachnet for an air fill. Wait until the truck arrives and top off the tires. Very efficient from a time and energy perspecitve.
Option III- Get my trusty portable Sears 150 PSI compressor and extension cord, add air as needed to all six tires (if required) and in 5 minutes I am properly inflated for my weight and I am safely on my way.
But then again, I do not have those special tires that do not need any air regardless of ambient temperature etc. in 40,000 miles of travel.
Man, do I need a set of tires like that. Would have saved me the $89.99 I spent on the compressor and freed up all 680 square inches of the compressor's footprint in the cargo bay.
To the OP, spend the meager $ on a portable compressor, have some peace of mind and keep on rolling, not waiting for your pressure to build or for Coachnet to arrive.
My 2 cents.
