Tire air compressor

Do people carry a compressor on board a Class A
for tire pressure?
What brand would you recommend?
Tires call for 110 and 90 psi.
Thanks

LOTS of information regarding your post. Do a search "compressor" to see the recommendation of RV owners.

I have air suspension but I carry a Viair 450 RV anyway as the onboard air is too slow.

I carry a Porter Cable CMB515 150psi compressor that works great. It only weighs 20lbs and adds air to the tires pretty fast. Others carry 12v Viair compressors but I found them slower than the PC.

I carry that Harbor freight $140 compressor in my class A. I run 90lb air pressure in my tires.

It only takes one time waking up in the morning to find you have a slow leak in one of your tires to convince you a tire compressor is necessary equipment.

I use the on-board compressor. As for portable compressors I consider the VIAIR 450RV the best out there. Pricey, maybe, but you get what you pay for!

Is it a DP ? Do you have air brakes? If so there is absolutely No reason too. To take up room and extra weight is foolish. Besides, You already have a expensive one on your rig. Install a fitting in the front and the rear and you only need to carry a short hose . Much more convenient and practical. And at a 110 psi it will do the job very easily. Check your tires just before you leave and if needed top them off while it warms up.

I carry a pancake compressor in my truck for my travel trailer. I was actually thinking about getting something smaller that would still do something well above the more moderate pressure I need (65 PSI). It takes up a lot of room in the bed.

The VIAIR compressors are very compact!

Depends. Usually I'm towing my RZR which I carry a Viair compressor in it for trail riding. Lately Ive also carried a Bosch pancake compressor in the RV as I've just forgotten to remove it from a prior trip, so it'll probably stay.
That said, I'm not worried how long the Viair would take to add air to the RV if needed. Even if it takes 30 min's, thats way better than having no compressor.

+1 for the PC
VIAIRs looked nice and a little more compact but a lot more $$$.
I used my engine block heater outlet for power and a 25 ft hose to reach one side of MH + toad. I also added a 8 ft hose from driver to pass side all with quick connects. I move my 25 ft hose to the pass side and do the same w MH + toad.
A little more work to set up but EZ Peezy when its time to air up.
