The second Swamp Monster is out and ready to go! This truck, this interior, this whole aura is off the charts. You don’t have to be a redneck to appreciate this thing but it does bring out the country in you. It’s a subtle but powerful detail with the interior that you have to see in person to really appreciate. With the money off on these right now you are getting all this and STILL under MSRP. Come check it before someone snaps this one up too!

⛳️ Registration is officially OPEN for the inaugural Birdies for Better Days Charity Golf Tournament!

Join us on October 5, 2026, at The Oaks Golf Links for a day of golf, community, and purpose as we come together to raise awareness for mental health and su***de prevention.

Birdies for Better Days was created in memory of my brother, Daymon, and serves as a reminder that even when someone seems okay on the outside, they may be fighting battles we cannot see. Through this event, we hope to encourage conversations, reduce stigma, and remind people that they never have to struggle alone.

💲 $600 per team | $150 per player

The proceeds from Birdies for Better Days will benefit NAMI New Hampshire.

And just like that the A.S.T.E.R.O.I.D. aka “Big Red” is gone 😢. Some trucks you don’t mind hanging around and the few days we had with Red were good ones 😂🔥💪🏻 Congrats to SauceBox and Aaron on the purchase. That truck turns a lot of heads so I hope it brings you and your business all the attention. If you see them around make sure to honk for support and check out SauceBox for some great food, obviously they have good taste 😉💪🏻🔥🛻 Roll Tide!!!
