Due to the large amount of interest in apparel (which is great) we made a store to make it easier to order! Few things:

•This will ONLY be open until Thursday, July 2. Why? So we can have the apparel by the Webster Co Truck Pulls!
•There are TALL t shirt options for the black t shirts
•There are youth options for t shirts and hoodies
•There is a separate category of toddler apparel

You may notice the pricing is very very affordable. That’s because we are selling it for less than our cost. We appreciate each and every one of you who supports our small business by ordering and wearing Big D’s!

This guy is officially on vacation for the week, so let’s play a game!

If you’d like him to get a dirty look from his wife, give him a call or text about your equipment! For best results, make it a long conversation. 🙃

If you want him to enjoy his time, or even better - if you want his saint of a wife to enjoy her time with him, call Big D’s best employee, Shay at 515-571-8116 to take care of your needs.

Much love,
Big D’s Diesel

We want to wish our best employee a very happy birthday! Shay is one of the few in the world who comes straight out of high school eager to learn, works very hard, and is a genuinely great guy. We are very lucky to have him part of Big D’s and look forward to celebrating many more birthdays with him. Happy birthday Shay!!
