Me personally, I have no expectation of the salesperson to be knowledgeable in anything other than where the keys are for the vehicle I want to test drive; my experience in 2020 looking for my current truck bore that out.
Conversely, I don't expect reliable information from a forum aside from if they had a similar experience with an issue and how they resolved it or if a particular aftermarket product fit and worked satisfactorily. Unfortunately too many forum people don't know S about what they are talking about and simply repeat what someone else told them or seek confirmation bias and repeat that.
I needed a wheel detailing stand to polish the wheels on my car, found a few but most were $200. Found on for $59 that looked identical to the $200+ versions but it had negative reviews regarding assembly. Given most people go to Ikea and buy something then fail miserably ay assembling it, I ignored the reviews and bought it anyway. Took me 10 min to assemble it and it works perfectly. Point, too many forum people are like Ikea shoppers/assemblers.
OP, I'll buy your truck
