Suspension:
TLDR: Its insufficient at a payload level, but within GCVW. Here are some calcs I ran, based on a calculator I found online:
| Curb Weight | 7,485.00 |
| GVWR | 10,000.00 |
| GCVWR | 27,000.00 |
| Payload | 2,520.00 |
| Towing Capacity | 19,000.00 |
| |
| Estimated Payload | |
| Passengers | 500.00 |
| Cargo | 250.00 |
| Total payload (minus hitch weight) | 750.00 |
| |
| Hitched | |
| Available Payload | -845.00 |
| New GVW | 10,850.00 |
| NEW GCVW | 24,850.00 |
| Towing Capacity | 19,000.00 |
I will add airbags to fix the sag and add the necessary payload capacity, within rear axle weight limits.
Power and drivetrain:
The Cummins engine is a monster, no big secret there. The trans handled the load seemingly fine as well. I found no deficiency in the powertrain at all.
Braking:
The truck brakes alone stand no chance in stopping a combined weight of about 25k#... good thing the trailer brakes are insane! I had to back off the braking controller to 4 to avoid the trailer JERKING the truck every time I touched the brakes. I think I could probably back it off to 3.5 or even 3 for flat land towing. I did a brake test with the trailer empty and the whole rig can stop pretty darn fast all things considered. I have no confidence issues with braking capacity.
Hitch:
I went with the Pullrite Superglide 24k hitch. It provided plenty of space between the cab and nose of the trailer when turning tightly around corners or backing it into the camp site. It wasn't cheap, but the auto slider is the only way I would go... couldn't see using a manual slider hitch setup.
Overall towing experience:
I would say that I started off VERY nervous towing this thing. I am completely comfortable towing my 30' enclosed aluminum sled trailer at quite a fast speed and even in shitty winter weather. This monster is a whole different beast. You can FEEL it behind you. When I was leaving the dealer with this trailer, I think I said "OK!" about 37 times before I made it out of their lot. I literally had to remind myself to breath a few times... its stressful at first. I drove it ~95mi home and another ~80mi to the campground. By the time we got to the campground, I felt pretty comfortable with it. I didn't exceed 67mph at any point with this thing hitched up... which is rare for me! 
Eagle's new rig.
