E450 valve stem extensions

[breal14]

I have a 24' e450-based class C, 2004 MY.

I will be doing a lot of airing down for beach sand travel to a campsite this summer. Getting to the valve stems is not easy. I can't even top up the fronts without pulling off the simulators.

Anyone have a kit they recommend? Lots of options, styles, varying price points and reviews are all over the place. Lots of comments on leaking.
I'm thinking a 2" extension will let me stick out of the front wheel and keep the simulators on (the wheels are so ugly without them)

and then a large/long dually kit for the rear, something like

This is the best sounding kit i've seen so far, but the ratings are not the best.


I'd also like to install a 'cheap' tpms at the same time.
I've been eyeing this one.

Amazon.com

it doesn't have to be perfect and i'm not willing to spend 300+ on some of those more fancy units. I'll still test the pressure at fillup time with my gauge, but want to be alerted to anything not looking right as we're driving.

I am getting a new set of tires put on in June so i would like to have everything ready to go, and if need be, done at the tire shop if anything needs to go inside the wheel (I know some more expensive tpms are in-wheel)

I appreciate any comments/feedback/links to products/etc.

I feel your pain.
From experience, whatever you decide on for extenders, do not over tighten--it distorts the seals and they'll leak.

Also from experience, forget that TPMS setup. You'll have a terrible time getting the right pressure in your tires!
When you screw on those caps (which need batteries changed yearly) you will loose 3-5 psi.
The solution is to over fill, then screw on the cap while holding the 'receiver' to see the actual psi, which may take 30-60 seconds to register. Then slowly unscrew to release a bit of air, tighten & see actual psi again. And on & on. THEN....you cannot check or fill your tires without removing the caps & starting all over!
The only solution to that is 'pass through' caps.

I had extenders on my 2020 Newmar with bad results. Got the 1 piece versions and no more leaks. They can supply you with longer valves for the fronts as well. TPMS is another story, I believe you get what you pay for on those, but I wouldnt run a RV down the road without them.

Thanks, that's the exact feedback i'm looking for. OK, i'll scrap those cheap tpms units.

Thanks for the link. Yeah, seems like they are all garbage. if it makes it easier to fill up, but leak, it's useless in the long run.

Looks like this is the kit i would need

Then it says it's hard to balance.
Then it says it's impossible to run the better tpms with them.


ugh.

I had a rubber donut in the outside wheel supporting the rear (dually) stem, front was just a slightly longer (maybe 1/3/4 or 2 inch at an angle on the front. Both supported the removable screw on TPMS with no problems. Only versions I have heard of with potential issues with the screw on type TPMS would be rubber valve stems, and valve stem extensions (non 1 piece) without a supporting bracket or donut.

I just ordered these. We recently had an extension fail. My research found to not use extensions. We will see how these work out.
Honestly I did not give the extensions a thought until one failed.

I will add. These were recommended on another group I follow.

When I got my new tires a few weeks ago, the truck tire dealership installed these yellow hard plastic extensions on the inner tires.
I have no clue as to whether they are sufficiently strong or practical, but they seem to work well.
