Pump it up!

[gfspiering]

I have used the Viair 40047 400P-RV Automatic Portable Compressor Kit for three snowbird seasons and love it.

We are using the following for our 110 psi LR-E trailer tires. Small, fits in pass through, 110 VAC (need generator or shore power), super quiet, with 50’ hose and Milton inflation head:

110psi is LR-G
80psi is LR-E

Without a doubt, the best portable air inflator I have found to date is this:

You can dial in pressures over 100 lbs, it uses standard 20v Max batteries. Dial the pressure hit play and it stops when reached.

I have a Fuzion 371 with G rated tires requiring 110 pounds.

Topping off all 4 takes mere minutes, since i got this thing I will never have an under-inflated tire again. It also fits neatly in the back seat toolbox of my F350.

You can get the bare tool for $99, some places less.

Viair is the gold standard. I adjust my truck and RV tire pressures generally twice a year (monitored via TPMS) Truck is 80 and 90 lbs, RV is 110. Check the Viair model number versus the max pressure you want. Some RV's go as high as 150 I think (bus?) The 400 should handle that if I remember correctly. The only thing I use for inflating all my 10 tires is the Viair.

We had someone give us a Kobalt inflator for Christmas a year ago. Presumably, it will do up to 120 lbs., though you may not want to wait that long. Our inflation pressure is 80, and although it's not zippy quick, I've owned other units that would strain longer just to reach 50. It's pretty light, runs off both 120V and 12V, has a light, cord and tip storage, and a preset with automatic shutoff. So really, I usually don't care how long it takes, I can just set it running and get something else done until it shuts off.

Earlier, someone asked why one would fool around with tire pressure on the road. My experience has been that I can start out here at home with 80, drive a few days, end up in another latitude, another elevation, another climate, or whatever, and be either five pounds high or five pounds low in the morning. On our most recent cross-country, at our destination we found ourselves uncomfortably low (beyond 5 lb.), so we aired up. When we got back home, we were high by the same amount, so clearly the issue was geographical. (The temperature was comparable, and the altitude difference was only 700', so I can't really explain it, given that a 5000' altitude change supposedly alters tire pressure only about 3 lbs.)

I use a Stanley Fatmax 1000 Peak Amp Power Station, it does not have to be plugged in so I can air check and air up the trailer tires very easily. It's rated up to 110 lbs & it only cost $80 at Sams. It will have jump starters and a light. I still carry jumper cables too.

I use a 1 gal 120v craftsman . It thanks a while but is light and compact. I want to add a little info to your notes when buying . A compressors pressure rating is at sea level. At higher elevations it drops off I found that above 6000 feet my 125 psi compressor only put out 90 psi and took longer to get there . I was in the high desert so low humidity probably contributed

Sorry, too pricey.

Nope - you’re right - my bad 😳

I have a Tsunami. It is small, very portable and will inflate a flat tire in about 3 minutes. The only bad comment is the gauge is not all that accurate but when you use it a while you know where it really is. This is my second inflator, I found the 12 volt ones just do not work.

When it comes to 12V compressors, you get what you pay for. If I was going 12V for the big rig, I would look at this first:

Check out all the videos from this site (TechnoRV.com) - very informative on some basic issues and equipment. I am not affiliated with this site other than I have made several purchases and I actually prefer them over Amazon Prime. If you see the Amazon ratings, people rave about these compressors. However, Amazon is really good about disguising the "older" model of things and you may not be getting the absolute best if you are not very specific/careful. In this case, you should be looking at VIAIR Model numbers that end in "RVS". The Amazon site shows the older model ending in "RV". Just a head's up...

For my big rig, I wanted a 110vac compressor so went a different route.
JMHO.

For all you cost conscious types this is less than $15 from an online store near you!

I love it! ������

Speaking from experience, the pump in flybouy's post #33 does not come with the optional sweatband. If you decide to go with that option, don't forget to order a couple of towels, the sweatband and a 6 pack of "amber adult beverage"...

And look at all the money you can save by not having to go to the gym for a work out!

Quick question on tire pressure since we are on the subject of Inflators .. does one increase tire pressure on the side that has a slide out since that side is usually a bit heavier or does one Inflate all four tires the same?

All tires equal pressure. The side to side variance in weight should not be that significant on a travel trailer.

Thanks.. that is what I have been doing . Was just curious
