That's too bad. Is the camper built so it can be moved to a new platform without extensive reworking?
A new TerraStar happened by today, good looking vehicle.
The camper and subframe were designed to work with most US medium duty trucks, as long as the top of cab isn't more than 60" above the rails. I would likely have to modify the CA, bolt on the spring mounts, and mount the cab leveling jacks (which would probably require some custom plates like I did for the Topkick).
Plugged fuel filter can be a huge part of the power problem. Check your cooling stack for debris and oil, I have seen more than one duramax that I pulled the radiator out and found the fins plugged with leaves and such, looked fine on the outside. Make sure all your shrouds and stuff are in place around the cooling units. A slipping trans will cause lack of power and overheating too. I have driven a few duramax pickups with big trailers behind them and they had plenty of power up hills.
I pulled the filter last night and found fine metal shavings around the bottom of the filter where the sensor screws in. My guess is that one or both of the LP fuel pumps in the tanks are shot, there's a ton of crap in the tanks from the upfitter failing to adequately clean them out after all of the grinding before the tanks got coated, or both. I'm ticked that the dealer replaced the filter less than 400 miles back and surely would have seen the same thing if they'd taken a moment to look.
I replaced the filter and took the rig out for a drive and got a few more pieces of info. First, it immediately ran like a new machine. However, I noticed a subtle sound when I put my foot on the gas, and got very distinct at 3000RPM. It sounds like a metal on metal whine or high-pitch rub. I didn't hear it before due to the stereo! And as soon as I pushed over 3000RPM, the same immediate loss of power and belch of smoke. My guess is LP fuel pump going- or gone- bad. I'm taking it in tomorrow to have the entire fuel supply system checked out. As for running hot, the dealer said they did a complete inspection of all cooling system components and they checked out except the fan clutch. Anyway, I'll try to work through the issues before swapping the truck out for something else. Thanks for the info!
