OK, got the new rig and am now starting to work through the inevitable (unfortunately
) list of issues that need fixed.
I have few smaller issues like the drivers side mirror wont adjust; I have a bad wind whistle at the bottom center of the windshield at any speed above 45 mph; the bedroom slide out has a 1" gap at the bottom when closed but the top has virtually no gap; air leak at drivers rear when engine is shut off.
Turns out the air leak was just a loose fitting on the airbag on that side, fixed by tightening it up.
Heres my big issue: When I drive down the road, highway or city street, it pulls pretty strongly and constantly to the right. Enough that you have to keep constant pressure on the wheel to the left.
I've driven OTR trucks and this is not my first motor home, so I know about road crown and drift caused by crosswinds. This is not either of those. The air pressure is set and verified at 110 in both front tires.
Camping World had me take it to a heavy duty truck center to check the alignment. The tech told me the alignment looked fine and was within spec on camber and caster but the toe-in was excessive. It was set at 1/4" and should only be about 1/8" (according to him) so he adjusted it to that setting. The shop thought there was a chance that a tire was defective so they put the right tire/wheel on the left and visa versa. This way if the pull was caused by a bad tire, it should now pull to the left.
I left the shop with high hopes but within 60 seconds of getting on the highway I knew there was still a problem. There was still a pull to the right, maybe slightly less, but now the steering wheel would also shake/wobble whenever it was in the straight ahead/neutral position. Not good.
Got back to Camping World and they installed some tire balancing beads in both front tires. Test drove it and it made it a little smoother but did not impact the right pull or the steering wheel shake.
The CW shop manager and I were standing there scratching our heads trying to figure out what could be wrong when I noticed the coach was not sitting level, by quite a bit. The parking lot in this spot was very level and you could see the coach was leaning noticeably towards the driver side. We aired down the suspension fully and measured from the top of the rear wheel wells to the ground and it was exactly 35" on both sides. We then started the engine and aired up the suspension fully, we gave it a good 5 minutes to make sure it was all the way up. We re-measured at the wheel wells and the drivers side was 37" and the passenger side was 39", so 2 full inches higher than the drivers side.
I'm wondering if this lean is causing the pull to the right? It's enough to impact the steering geometry sort of like bump steer. Has anyone heard of this issue and what might be causing the lean? Any other ideas on the pull to the right?
Note the fuel tank was 95% full, the water tank was totally empty and we had nothing else loaded into the coach. So, I know it isn't heavily loaded on one side causing the lean. Both of the slides were fully retracted and closed too.
Does anyone know if there is an auto-leveling function in the air suspension? If so, maybe that is set wrong. Until I get under it and start rooting around I cant understand why an air suspension system would be sitting unlevel unless the airbags on the drivers side are receiving less air pressure.
