Front Airbags not filling at idle??
I start the motor home in the morning and let idle to let it warm up. The rear bags inflate to above 100PSI. The fronts only go to about 60psi. As soon as I go about 100 feet the fronts inflate to ...

Start the engine. After 20-30 seconds, engage high idle (around 1100 RPM).
After air pressure builds, you are "free to move around the country".
Sure, this means under light load until coolant operating temperature is reached-- like exiting CG, low speed driving. If you overnighted at a freeway entrance, yes, stay at high idle until temperature gauge is at least half way to normal operating temperature before jumping on it.
Also good advise. You need to know what your cut-out pressure is. Usually around 120 psi. Both front and rear tank need to read that psi and you hear/ feel the compressor unload. At a minimum you would release parking brake, pull foward about five feet and make a brake application to test system function. Then your ready to roll.
My apologies if you know all this. Just want to make sure your not idleing a bit then hitting the road before system reaches full pressure.
Other possibilites off the top of my head, air compressor not moving volume of air it was perviously? Air ride/dump Valve sticking which allows air to bleed, once you start moving rpm increases moving more air into system and seats valve.
