Question Washboard roads airing down?

Hello friends ,

Has anyone had experience with their van ride down a washboard rough road for 5 or more miles ? Iím considering to head to Alabama Hills, CA and read their roads can have some pretty rough parts. Iím in a roadtrek 190 Chevy chassis, so Iím not sure if I can make it. The stock tire pressures are 60 front 80 rear.
Any fellow campers have any experience with these kinds of roads and any tips or recommendations?
Thanks in advance!

Thanks for the reply. Do you air down or you just let it rumble?

On the way to Lone Pine Campground and Mt Whitney, I drove thru Alabama Hills. I had no problems and enjoyed the drive.

Too much hassle to air down. Then air up again. Not even sure my portable generator can get tires back to 60/80psi without burning up.

I just avoid bad roads if I can, slow way down if I can't. But yes, rough roads are rougher in an rv.

I don't consider myself as a wimp about back roads, and have been on some that might be better suited to high clearance and four wheel drive. However there was one eight mile stretch of washboard gravel that we started on in our '09/10 Roadtrek C190P on that was so bad that I turned around after a mile or so. I tried all sorts of speeds to try to find one that didn't jar our teeth out, but just couldn't find anything comfortable. The road was not like a Jeep trail by any means, it was level and flat as I recall, but just had those ridges across it left regularly by some sort of road grader. It seemed that the frequency of the ridges vs. the suspension just didn't play well. I did not air down, and wouldn't out in the boonies unless my life depended on it.

A few years ago we hit a long stretch of washboard in the South Dakota Badlands. I remembered a college prof in an engineering class say you should speed up to get the vehicle suspension acting at a higher frequency to reduce the motion. So I tried it and it worked, though I think we were going about 35-40 mph and kicking up dust. Encountered a similar road last year in New Mexico and tried it again. As before, things smoothed out, but I started to slide a little bit sideways which was very scary. So I slowed down and drove the rest at 5 mph. So no more high speed driving on washboard from now on. Besides, what am I in a hurry for anyway?

Some roads, just don't get graded correctly & through a combination of harsh weather, the use of special vehicles & a poor base to begin with (rock & clay), they make live Hell in an RV.

Sometimes a perfect road can become an impossible one 30 days later.

It could also be a symptom of your Rig needing an inspection.

I am an Adventurer but the book*, THE ROAD LESS TRAVELED was NOT written by a Class B owner.

My vehicle is heavily modified because as Wes so accurately states, RV Travel is always an adventure ...

*yes, I understand the book's original intention about psychology & the choices we make

Hi Kon,

If you have not already driven your B on LOUSY surfaces, you'll learn as is discussed here at times: There are 2 whatevers, the van and the rv, home, house behind the front van seats.

The rv, home, house portion is glued and screwed together along with all of those pieces parts glued and screwed together.

You will decide what you'll put your B through.

Bud

Yeah, I definitely donít want things to come loose.
If I do decide to air down, what would be considered The ideal psi for the tires?
I do have a portable Dewalt 2.5 gallon air compressor that can air back up fairly quick and easy, but still wondering how low will I need to go.
Thanks again

I was on one of those roads a few months ago. Didn't look bad, but those Caterpillar tracks are the worst. A relentless drubbing on every part of the van.
