I have been a food truck owner for some time and my old food truck was grandfathered in so I did not require TSSA Cert. I modified my old food truck and was ordered by the TSSA to upgrade the food truck to the new code?? I have no idea how to do that, searched TSSA database and found MMR Anderson and they made this paper heavy process painless. Eric and John got my truck up and running and met the TSSA Field Inspector and got my orders discharged and a new FSD certificate to operate. Great job guys.
