I have a 2017 hawk flatbed, just like the one dave had, previously mentioned in this thread. Matter of fact, after my wife and I walked through his, she insisted I sell my land cruiser and adventure trailer and build a truck like his. So we did.
I did build mine on a 2017 ram 3500 though, for the leaf springs. Not that coils are bad, but I knew I could work with deaver springs to build my rear spring set to handle all the weight. Carli Suspension also dialed in my shock tuning to work together with the deavers and to handle the weight like it should. And the ride is amazing. Considering I have a family of five, fully loaded right around the gvwr of 11k pounds, I can boogie out in the dirt. The torque of the cummins and the upgraded suspension make it sooooo much fun to drive - which is a huge priority for me. I have to enjoy driving it.
The 1 ton cummins ram, paired with the flatbed hawk is a match made in heaven. I'm a die hard toyota fan, had built tacomas and a landcruiser prior to this but I wasn't confident in a tundra with a flatbed hawk. I can cruise the highway, headwind and all, and still have passing power.
We've been in this setup a little over a year and it's been simply amazing for our fam. Super functional and efficient. It's was a lot of work to take 3 boys camping, now it's easy peasy.
My oldest is 14, and had a major growth spurt. We can all still sleep comfortably but we're now considering going with a hallmark flatbed. They offer a bunk over the dinette, along with the cabover, which is 3 separate beds. This would be a major upgrade for my growing kids. They also offer air conditioning and larger fresh water tanks. We would still keep the ram because we know it's up for the task but we'd likely rebuild the flatbed and put the hallmark on it.
