I think this sort of thing tends to happen organically to an extent; folks watching out for those with less experience or some issue that they've brought up. I would encourage anyone and everyone to bring up any issues you may experience as soon as they're discovered, no matter how small. That little shimmy, that burning plastic smell, that weird feeling in the brake pedal... any of them can be indicative of some serious issue that someome with more experience or who isn't stressing out about it may recognize as something they or the group can help you address. There is no shame in asking for help or a 2nd set of eyes, ever. Most everyone loves checking out other rigs anyway.
I'm not sure how an official tech inspection would work, this isn't an official event where there is a defined process for such. To me that brings up questions such as:
- Who administers it
- What are their qualifications
- To what standards/specifications is the inspection performed
- Who is responsible for the results of said inspection
- Do we reinspect deficiencies found
- Do we need to document them, and how
- How do we manage what rigs have been inspected and when (arrivals mid-trail from the other side of the mountain, etc.)
- Does this inspection have any legal significance once performed, and to whom, and would this deter people from performing such inspections
- Etc. Etc.
I'm more than happy to help anyone with anything or be a 2nd set of eyes, but I would have some concerns about trying to implement a legit inspection, given the goals and status of this gathering. I'd rather not support a push to make this event something it's not.
Get your truck in good shape, ask for help, don't be a dummie and take something on the trail (or road) that doesn't belong there, and let's have fun in the mountains with our old rigs and each other.
