That isn't really how thieves work, I don't think.
People looking to thieve anything (not just cars) are looking for quick and low-risk "targets of opportunity". If your truck presents any difficulty or additional risk of being spotted or getting caught, they move on. If it's parked in a well-lit area and people are around, they won't try it. If you're parked in a dark parking garage in the middle of the night, then there is some elevated risk.
I saw one list of most commonly stolen vehicles AFTER adjustment for # of that make/model registered, and it was the Jeep Wrangler at #1 - probably just easy to gain entry to without arousing suspicion.
The most common vehicles stolen otherwise are Camry's, Accords, Civics, etc. They aren't distinctive. They present extremely common targets for a thief who is well acquainted with the process of stealing that particular make and model. Often these aren't professional thieves, though there are sophisticated car theft rings out there (particularly in border states). They are often some loser who learned "how to steal a Civic" from someone else, and tends to stick with what he knows.
If thieves are looking for trucks they tend to steal American full-size trucks, later models are good because they contain parts that aren't manufactured anymore and are generally easier to steal than newer ones. Plus there's a more abundant market for the parts from an F-150.
Anyway. Just what I learned from some reading I did once.
It's not that I think the OP is dumb for getting an alarm. I just don't think "If they want your vehicle they will take it" is totally true. They have their own motivations and calculations they do around it. They follow rational processes. You can guess which car on your street might be more attractive.
