I drove full-size pick-up trucks for over 20 years and EVEN FOR ME it was tricky to maneuver these trucks in the parking garage, especially the 4 door variety with those long beds. So how do you think a 19 year old rookie valet will fare at this?
While I was a valet driver, if a rookie was told to move a full-size pickup, like a Ford F150 or a Chevy Silverado, I could sense the apprehension, the concern, the lack of confidence. They have to learn to maneuver them sooner or later, though. So... your truck might be their first!
And if you happen to have a manual transmission truck — oh boy!
Valet pay is ridiculous for the skill that is required, as little as $2.13 an hour in 19 states, which is the federal tipped minimum wage. Lousy pay makes the job low value. Which means a lot of workers don't take their jobs seriously, because it's just temporary employment.
When these low paid workers quit or get fired, more new rookies (with no full-size pickup experience) come in. This constant flushing out of talent means true experts at driving big pick-ups are probably fairly uncommon in this industry.
Here is a common type of mishap that big pickup trucks get hit with while under the care of valet parking services:
If the truck clears the height limitation barrier at the entrance to the garage, it doesn't mean the roof of the truck is safe. (I found that out the hard way.)
Every valet operation is unique. No two are exactly the same. You probably have no idea whether a particular valet operation has an easy parking facility, OR an extremely challenging one with difficult, tight turns... where it is a damage claim nightmare and the valet company wants out of the contract.
In summary, when a situation requires that your big pick-up be valet parked, I recommend you use the influence of a substantial paid-on-arrival gratuity to keep your truck parked up-front, so that your chances of damage and grief are substantially reduced.
From what I have seen, valets generally have difficulty with big pickups and big cargo vans. And if you are going to let them drive your truck into the garage, you are really daring life to smack you with a stressful event.
