My 15 pulls our 44' Northpoint with ease. The L5P has a little bit more HP and TQ so it should be even better.
The Banks thing is kinda funny. 20 years ago modifying a diesel truck was just barely getting started. I put the biggest, baddest kit Banks had on my 99 Cummins. That truck would rip, but I had WAY too many issues with their stuff and ended up ripping it all off and sending it back. I had it on for about 2 weeks. After that I bought parts here and there and modified things myself. Remember, 20 years ago the internet was DIAL UP. Broadband was like prototype for customer use. It didnt take long and my cummins was making 750HP on fuel alone and all stock internals, block, crank, rods, pistons, cam, valves, and rockers. Aftermarket parts were injectors, valve springs, fireringed head, head studs, turbos, and a fueling box. Best part was there was no emissions crap or really even standards back then. Unfortunately the EPA has it in their head that it's up to the US people to save the world of all its emissions issues and unfortunately the American people are gonna pay for it.
