Both the trailers you are talking about come in on the heavy side. Setting up the truck to tow heavy in only part of the issue. You have to also have to make it capable of slowly down and stopping it. Think exhaust brake! So you are looking at almost 8-10K to make into a viable tow truck for trailers in the 12K range.
Been there and have the t-shirt, hat, merit badge etc for building my 2001.5 RAM to tow a 12,400 trailer.
1. Gauges
2. Exhaust
3. Exhaust brake
4. Injectors
5. Turbo
6. Transmission/torque converter (I did it twice in eleven years)
7. Controller to lock torque converter
Addition for you.
8. Wide rims and LT265/75R16E tires rated at 3415.
9. Depending on rear suspension - Air Bags.
10. 5th wheel hitch.
The order you take in doing the up grades has to be carefully layed out or you repeat things again with a different componiet.
Jump in the truck and go spend some time talking with these guys.
