Compressor Recommendations

[MapNerd]

Wow, lots of great food for thought. So a couple of things happening now.

1. Four corner weight is happening tomorrow. So I expect my pressures will drop on the after doing that and knowing exactly what pressure to use. I’ve been running at max psi as it came from the factory (I know, I know...). Found a spot nearby where I can get my four corner weight.

I don’t have my TPMS sensors on the stems because I ran into an issue with the valve stem extenders on the drive wheels not giving me enough space. So it’s not a tpms issue.Ordered longer valve stem extenders - single piece they will be here tomorrow and also get installed.

Also did a thorough inspection of all tires, outside, tread and inside. Got nice and dirty crawling around like a pig in the mud, but couldn’t find any tire damage and played with each valve stem to see if I could detect and leaks, couldn’t really find anything of note.

Hopefully, between getting the pressures calibrated to the weight and swapping out the valve stems, the issues will be resolved.

Receipt looking thing is Newmar's four corner weight at FPU. RVSEF was later, then Dec 2018 was the Flying J weigh in prior to HWH Active Air install.

Yup. Makes sense. I am right at 14000.

So got our four corner weights done. We're 400lbs over on the front axle . Looks like we've got a bit shuffling to do but overall, pretty satisfied. PSI's shown are what we'll be putting them at. We know rear steers could probably go down to 75psi but we think we'll do 80 just to keep life simple. Previously we'd be running 120 everywhere in the absence of any real knowledge of what our weight was.

A little concerned about the front being so overloaded by 400lbs. I'm not sure how much we can do about it though. We don't have anything particularly heavy up front. I think the heaviest thing might be the domestic freezer and slide out. Tools, compressor, winter clothes - it's all at the back just before the drives.

I know as we burn fuel that will lighten a bit, but with diesel at 6.8lbs/gallon, we'd not be underweight on the front until we're at a half tank. As for the TPMS and valve stems, the extenders weren't delivered on time. Should be in some time today, hopefully that will solve the issue with pressure loss and allow me to get my sensors on the wheels already.

Just curious, was this done with your whole family in their normal seated positions?

 

[MapNerd]

@Akdare Yes. Everyone was in the coach. We even moved the coach off of our site and took it to a parking lot that was more level. Everything was packed away the same way we drive it.

We weigh at the beginning of every trip. Lucky for us our first fuel stop has a CAT scale. We use the CAT APP which allows you to manage the entire weigh operation from your phone. No need to speak with the operator of the scale. Quick and easy.
We have a Viair 400P Compressor hardwired to 12V in the front door side compartment of the CanyonStar. The air line extensions supplied with the Viair reach all the RV tires and the Dolly tires. I try to make it as easy as possible to use so no excuse not to air up. Also I installed Anderson Powerpole connectors so I can quickly remove the compressor and use it in another location using the original battery clamps.
If you are not familiar with Anderson Powerpole products they are great, easy to use and reliable 12v connection. These are used extensively in Ham radio. My call sign is W4JCH

Here is a quick tutorial using Powerpole products. The can handle up to 45 amps 12V.

I have been using Anderson PowerPole connectors for at least 20 years in ham radio and other applications. They are terrific 12VDC connectors. As you've probably noted in my signature, my callsign is W7DHC (licensed since 1974).
