New toy - viair 450p air compressor

[Himcules]

They make a smaller version as well, the 400p. And both sizes come in full rv kits.

I got the regular non rv kit because Amazon didn't have it on prime and I need to leave soon for an 1800 mile trip. I can always run this from my jeep out add the extra hose easily.

I love mine!!!

My Berkshire has an air outlet in the generator compartment. I coiled up a 50 ft. air hose there which can do everything for me. An extra air compressor makes for more portability if you feel that you need that..

X2, plus my "Rube Goldberg" device.

i've tried that and didn't have the patience for the cycling nor the noise of the engine running while i'm trying to inflate all 6 tires. my fronts dropped to 80 psi while it was in storage over the winter since last summer. that would've taken me a couple of hours to do it that method... i'm lazier than i'm cheap

for the record, i did not need the "rv" specific kit to air up all 6 tires. the single 50' hose in the non-rv kit reached all my tires. i hooked the compressor to the house battery bank and made sure the hookup cables were all the way out. i then just walked to the furthers tire (passenger front) and the hose went under the front and i still have 3-4 feet of hose with the chuck locked on. the second extended hose would've been easier, but it's not neccessary.

We discussed this at Camp Freightliner this week and while technically you can do this none (not even the folks with the big Newmar's) were having a great deal of success (PSI over 100 & Cycling)

The group consensus was the Viair 40047 400P-RV as the best all-around pump out there - it can inflate to 150PSI and has a 20 min duty cycle before resting--that's a lotta inflating!

Oh no, I need to buy a Berkshire to tow my 5th wheel...

I love my Viair also...

BTW you would have to go back to a TT, the Berk can't accommodate a 5er hitch

Unless you wanted to flat-tow a 4x4 P/U...now wouldn't THAT be a interesting, almost 100' long sight!?

I have used my Viaair to inflate more tires for other helpless RVers than I can count. I have only used it once or twice on my own 5er. It is a quality piece of equipment. Reasonably quiet, powerful and has a long duty cycle.

Great choice.

Hey Bob, Camp Freightliner is where I got the design for the Rube Goldberg device...lol

I have used mine a number of times and love it however, for what ever reason I blow fuses on the compressor. I would suggest you buy extra fuses--mine takes 40amp. They are very hard to find. AutoZone is the only place I have been able to locate them.

Has anyone considered inflating with nitrogen? There is very little fluctuation with temp using nitrogen. The only drawback I guess would changing pressure if you change your weight drastically and finding the service for it.

IMHO it's a waste of money. Have to adjust air pressures too often.

Ben,
This has been discussed before and after we came to the realization that the atmosphere is already about 78% nitrogen it would not really be worth the extra money to have pure nitrogen put in the tires. This, of course, would be a personal preference and if someone feels that it is worth the money, they should do it.

BOY has this topic been beat to death on the forums!! (Go ahead and search for Nitrogen filled tires )

This was another topic of discussion at Camp Freightliner and the take away is why bother?

I agree. After all, good 'ol air is 78% Nitrogen

yep

another thing to consider is that tire air pressure should be measured and adjusted cold. how many people have nitrogen tanks at home or have a service that drives to their campgrounds to adjust their tire pressures?

when you drive your rig in for service, tires are going to be hot.. especially since most owners live a good distance away from their service centers... they aren't going to sit and wait till tires are back to ambient temperature to adjust them

[grumpy0374]

Solution...just release 22% of the air in your tires. and replace the 22% with nitrogen. That will give you 100%.
Maybe we should try replacing the air with helium. This would make for a lighter rig, and make for great gas milage increases.

Rich,

When did you go to Camp Freightliner? I am wondering if Opinions have changed?

I'll bet Mike Cody taught you that Rube Goldberg design though!

Did you ever go to Camp Freightliner II?

[BamaBob]

Heyyyyyy.....


It just occurred to me that folks may be inflating tires improperly (Another thing we learned at camp Freightliner )


In almost every case you should NOT inflate your tires to the pressure on the tire card. Rather, you need to get your rig weighed *as driven* (i.e. full tank of fuel and whatever you normally carry in your tanks, basement, and living area) at each tire. Go to the following table to find your correct tire pressure based on axel weights:


Michelin RV Tires | View Michelin RV Tires load and inflation tables for motorhomes and recreational vehicles. | Michelin RV Tires


Also take a look at load imbalance if you are several hundred pounds heavier on one side of the axel than the other, you really should try redistributing weight in either the basement or the living area.
