Considering Newmar with Cat Diesel - heat?

I am considering a 2003 Newmar Dutchstar with a Cat Diesel that has become available in my area. This unit has 33,000 miles on it, 2,000 hours on the Onan. This unit belongs to a neighbor friend of mine, and I have been around this unit for about 10 years now, camping together. I have spent the last several weeks going over this unit, checking it all out anyway, and then suddenly a co-worker tells me that I should be aware that "DIESELS LIKE TO OVERHEAT IN THE HOT SUMMER IF DRIVING IN WEST TEXAS HEAT 110 DEGREE WEATHER".
I have never heard of this at all. My gas unit has never overheated but the Onan gas generator did once.
My question is, IS THERE ANY TRUTH TO THIS ? I mostly drive in the summertime because my wife is a school teacher and we mostly get to go on vacation in the summer when it is very hot. We like to travel west (which puts us crossing Texas).

Ok,
You stated you've been around this RV and been camping together for a period of 10 years, correct? If so, did you actually travel together? If so, did you see or hear the owner EVER complain about ANY overheating conditions in that 10 year period? If you've never heard of seen him complain on any heating issues, then logically, it's not gonna heat when you purchase it. Now, of course things wear out, get stuck and all that so, the "Potential" for overheating is there. But, the probability should be way down.

I'm also assuming that you more than likely, being a somewhat close friend of this neighbor, know the service and maintenance history of this coach. And if that's the case, they you already know this coaches operating circumstances, correct?

You kinda need to sit down with this co-worker and do a bit of explaining on the fact that NOT ALL DIESELS are the same, operate the same, have the same issues and troubles, and more. There's a whole ton of CAT owners on here and other RV forums that are completely happy with their CAT engines. All you need to do is ask.
