If you get your permit here, do you need to carry your title with you to the border?
Answer: No
Optional Reading:
If you obtain your vehicle permit at a consulate, the only remaining piece will be the Tourist Visa, which you will obtain at the Aduana (customs) office at the border.
You will not be required to carry your vehicle title, in fact it is not a good idea. It will not be needed nor asked for, and it will be just one more key document to keep track of.
If you obtain your vehicle permit at the Aduana, you in fact do not need a vehicle title, just the original vehicle registration which must match the name of the operator AND the name on the credit card you wish to use. If you are "Richard Johnson" on one document but "Rich Johnson" on the other, that won't cut it so get that addressed now.
On vehicle titles used to obtain vehicle permits, I always highlite the VIN number and my name, and I sign the registration in blue ink somewhere in an open space. Sounds wierd, I know, but border officials can be officious and they also like to find what they're looking for fast.
Don't forget to bring your passport for your tourist visa, or a raised seal birth certificate (not a certificate of birth - they're not the same thing, and the latter won't work for you).
Bonus Tip: Call your credit card provider the week before the trip, and put a travel alert on your card. Depending upon the bank, you may run into a hold on the card if you fail to notify them in advance. Dealing with that even in a border town will be frustrating and you'll be calling the bank while everybody else is processing though. If you have two credit cards, bring a second one as a spare and hide it on your bike.
I've seen vehicle titles signed over from one rider to the next at border crossings to facilitate entry but that's another subject entirely and you won't even approach that complicity.
Just bring your drivers license, your registration and a credit card with the same name on each and you'll fly through Aduana.
