6.6L Duramax Deisel

Lb7 was good but low on power Lly was terrible, lmm was good.

My 06 is a beast! Great truck. What year?

Probably 2013.

Mine is a 2005 and I like it. No issues yet. I pull a 15000 Lbs 5th wheel and get around 11 MPG.

I had a 2011 2500 CC 4X4. I called it a "Hangar Queen" due to the fact it spent almost as much time in the shop as it did being used. Numerous lites for the DEF, Shifter cable broke and the 4X4 cable kept falling off the shaft. Finally gave up and went back to 6.7 Rams problem's solved! Down sized from that to a F150 Ecoboost CC 4X4, Happy so far.

There's probably more LB7's with injector problems out there than there are LLY's that are "overheaters".
Pretty general condemnation....
IMHO;)

Good engine? What's your experience?

Wish I owned one!

I owned a 2003 for a few years. I think that was an LB7 during that timeframe. The biggest drawback was that there were a lot of injector problems and they were very difficult to replace. That situation was improved in later versions of the engine, but some of them had their own problems. My own experience was that it ran great and pulled strong. I didn't particularly like a lot of design features of the rest of the truck. The engine and Allison tranny were flawless for me.

What I am interested in is a Tiger CX 4X4 motorhome on a Silverado 3500HD chassis.

Unless you plan to tow with it, or need really good performance at high altitude, the diesel is overkill in a Tiger, IMO. The current 6.0 liter gasser has almost the same torque & HP as my older 8.1, tho' probably at higher RPM. Save yourself some $$$.
