Pulling 5500# travel trailer EOT & EGT Temps?

[Switchrider900]

Just wondering what I should be seeing for EOT and EGT temps pulling a 5500# trailer?

Have gauges so I was seeing 212 EOT and around 208 EGT temps today just driving in the city, was just picking up a trailer today for someone, but thinkng of buying one. So just wondering what would be "normal" operating temps for pulling this kind of weight.

It was pretty warm today also!!!

when pullin my 8k travel trailer on normal highway driving they stay between 210 ans 220 for both..... whn pulling big hills or long grades ive seen my water get as high as 240 but go straight back down in a matter of seconds to the 210 range... when driving in town my water stays lows but my oil can get up to 225 range

If your oil temps ever get more than 15 degrees hotter than your coolant temp your oil cooler is clogging up and it is time to get it rebuilt before bad things happen and it costs you more $.

What are safe numbers to stay under for stock head bolts? I mean in Boost and EGT terms.

High EGTs aren't a head bolt problem. High EGTs melt pistons. Typically you are not going to over boost the engine with a stock tune. I don't think you'll see much higher than 31-32 psi and that should be ok. I think a lot of head gaskets are lost due to leaking egr coolers. Then you get coolant in the combustion chamber resulting in steam and high combustion chamber pressures. Could they go for other reasons yes but the above makes sense to me.
