GM back in the '60s era were using a trailing arm with coils. I had one and carried truck campers.
I was very surprised when Ram announced the new coil spring 2500 truck. However those that use the coil spring 2500 truck don't seem to have any problem with loads in the bed like a GN trailer or 5th wheel trailer or a bumper pull unit.
IB516 has said his 2500 coil spring truck carried his 5er with about the same sag as his previous 3500 SRW Ram/Dodge.
The old GM trailing arm setup had the coils very far inboard. This allowed for a huge amount of body roll. If the rear shocks were bad and it started swaying it reminded me of a high speed bazz boat chine walking. The only way to stop it was brake and slow down quickly.
GM did have a three leaf half spring set up for a overload/stabilizer set which stopped body roll.
The spring set were cut in the middle (half spring).
They bolted to the main frame rails behind the rear axle and contacted a pad on top of the axle tub out board from the coils. These were a option from GM.
If I was in the OP position I would look for a TC with the lowest profile that would work for his needs......and not exceed RAWR...wheels/tires and rear spring pack capacities
