Driving in the heat!

Will be leaving Nashville this coming Friday and heading toward Denver. I understand it will be 95 Is weekend. I have a 2008 Monaco Knight with an isc engine in it. I have never driven it in 95 plus heat. It normally runs between 180 and 188 degrees. After driving all day the trans will run around 172 degrees. Should I expect to see the engine and trans run warmer or the same?

Thanks.

Steve

If the cooling systems are working as designed the operating temp should stay pretty much the same ...likely go up a bit on climbs, but there aren't any huge ones before Denver unless you go up I-25 over Raton Pass. If so, just gear down and keep the rpm up and it should run fine. And you may want to run the generator so you can run the house air ...I definitely would.

Will running air in bus, not house air, make the engine run warmer?

Possibly but I would encourage you to turn the gennie on and run the roof air(s) as it should be more comfortable and will only use about .6gph. Save the engine power for the road and hills and excersize that generator. Our gennie is running 9 times out of 10 when we're moving mainly for the reason I just mentioned.

Yes, the engine a/c might cause temp to rise a bit. When I worked in Death Valley I always advised people to travel with gen running and house a/c to help the engine stay cooler, especially pulling grades.

I agree, run the gen and be comfortable. We are leaving 3rd week in June and plan on 4,500 trip in the heat, top on my list is to clean radiator and coolers.

I have a yar, and 17,000 miles since i bought my identical 08 knight. Over hill and dale, up and down the toughest mountains the east side of the country can throw at us.

My temps, on both the gauges and alladin system are right with yours, engine 180-185, trans 10 less always.

We run the dash air on full blast.

If the kids in the back complain really loud, i've turned on the genny and front house a/c, but this has been rare. 2 weeks, we're off for utah, counting the days, can't wait to see how the knight handles the real mountains.

When headed west into a head wind the temps should be monitored also.

The winds are only out of the west when I'm heading west. When I'm coming home, they are always out of the east!

the dash air will not cool the whole coach. mine does a fair job in the driver/passenger area. because of the animals, i run the gen and house air.
as all animal owners know, i as husband come below the animals on the totem pole.
their comfort is uppermost on dw list. 48 yrs of marriage has led me to believe if it doesnt matter 10 years from now, its not worth arguing about.

Azpete,

Your 10 year is a good one. I should try to follow it.

AZ Pete--

Just in case you didn't know (AS OPPOSED TO KNOWING AND NOT SAYING IT--)

We as husbands are lower than the low on the totem pole. If you will look just below the compacted base material just below the foundation, is where you will find the HUSBANDS.

On a good day!!

I knew it was true with bicycles, now I believe it is true with RV's, 75% of any round trip is up-hill!

My ISB (AKA the little engine that could) will sometimes push a bit over 200 degrees when heavily loaded for awhile. When I see temp climb over 195 I downshift to get the engine at 85% or more of max rpm, and turn off the dash A/C. If temp continues to climb, I drop the road speed.
