I'd go 250 miles just to get things started. Then load the hell out of the
truck, pull a couple of cars and a boat all at the same time if you are so
inclined. Loading helps seat the rings. If you don't load the engine, it'll
take years to fully break it in.

No, I'm not exaggerating.

I have had three Dodge trucks so far, a 92 Dakota, a 02 RAM and a 04 RAM,
none with diesel.

Loved them all, but now we went a bought a bigger trailer so my wife and I
just bought a new 07 RAM SLT quad cab 2500 with the 5.9 Cummins diesel
tonight and will pick it up on Tuesday.

Now before I get flamed silly, I have read, searched and hunted a pile of
newsgroups, Goolge etc and cannot find consistant answers to the simplist
questions for a new diesel owner. No manual yet either. So this is why I am
asking the group.

1) what is a break in period before I can tow the trailer. It is a 7200 lb
travel trailer.I was told right away by the dealer and after 5000 kilometers
by my neighbour who has an 05 mega cab 3500.

2) when should I change the original oil?

3) I have been told three answers to this question, how many miles
(Kilometers) between regular oil changes should I expect? one guy said
12,000 kilomters (7000 miles), another said 10,000 kilomters (6000 miles)
and another said every 5,000 kilomters.(3,000 miles). I am used to changing
the 04 Hemi every 5000 kilometers.

4) Can you really run any of the diesel fuels in the 07 5.9 Cummins or must
I only use the Ultra Low Sulphur fuel.

any other special things to watch out for?

I promise I will read the manual when I get it, but I just want some real
world opinions. I know these sound pretty simple to most of you, but
