majorgator ...
I am ( somewhat ) sorry that my question seems to offend you this much .
I did , in fact, search for BULLET PROOFING RESULTS before posting the question, and found ZERO comments where the person commenting actually ever had THEIRS done.
THAT .... is why I asked.
Do YOU actually have some useful info on this VERY SPECIFIC question ?
You told me, earlier, to go somewhere else for the answers I seek, but I choose NOT to ! I do not want the ramblings of the 'dirty baseball cap & chew-backy crowd' ... I want the experiences of RV owners who have put this truck / engine to the same type of test that I plan to.
I invite any USEFUL info you may have ... ON SUBJECT ... otherwise ... BYE BYE !
