I have been reading this forum for about 7 mo. and it is great but I don't see a lot of praise of the truck . I purchased my 2500HD D/A CC in July and have pulled my TT (34 ft. 2 slides 11k) on 3 trips about 2000 miles total with no problem with the truck...This is the first truck I can set cruise and go....
Now the story that caused this letter..... Been having trouble with TT brakes not releasing after stoping D/A did not care would take off any way, then they would realease. Yesterday while being the good husband I was backing TT in by the house...... Hit the house with TT.... SICK only 8 mo. old.... Took it to local body shop to muck for him to fix...coming home brakes locked up while moving ...I had to pull this TT 45 Miles (with no Brakes) to the dealer....
This truck stop with no problem .. It did not know it had a trailer behind it...
I said all this just to say this is the Best all around truck I have ever owned.

Sounds like you are having a lot more luck with your dmax than your travel trailer!

yes when it rain it pours..

So far my 04.5 is the best vehicle I've owned, bar none. 10K miles and not hiccup. Totally a stock unit and remaining so.
