Dude I have been there with the much loved vehicle getting stolen. It may sound hard to figurte, but if I can give ypou a little advice, it's work but you'd be surprised how such works.
1. fax info and pictures to the border patrols asking that they send and post at every US Border. asking nicely will work, sounds weird but the only way tht truck will stay in one whole piece is it's either been hidden for long range future use or it's on it's way out of here, hiway patrols may also send the info around, thye all have computers now in their cars so, asking nicely at the local state patrol office and maybe even a couple dozen dougnuts(dont-laugh) and some a clear 4x7 close-up pics with info written on it so it can be posted in one page with contact info, reward (even small) will help, believe me
2. local tv and radio. seriously a[[roach ;local tv and tell them about your huge investment, much loved family truck, the more who hear thje better chance someone saw something
3. door to door in your neghborhood, someone may hav noticed something out of the ordinary, asking nicely and ;leaving your number may just jog someone's memory
4. call or fax pic and info to every salvage yard as you can, also asking a larger ;local yard in person to get the news out over their network, for these guys know people from next door to every attaching state.impress upon oithers the personal value and hope for return, get people on your side
no qusetions asked reward notice with pic in paper, you dont have to aks questions, not sayin your brother or friend or w/e may want to of those who do come forward
5 most people get caught doing crap by talkin, or their friends, g/f mad wife, etc talk or squeal, use this knowledge, offer a little money and open convo, make sure you have a number someone can reach you 24/7.maybe even buy a cheap use cell phone only for this purpose.when it rings you know it'
s about the truck and nothing else
6. Wish we could help,. I know all here will do whatever they can, theives suck!
