"Fancy"......Yes, your coach will shift because it doesn't have enough power to climb a steep grade in top gear. Even cars have to downshift, often it's smoother and you don't notice it.

Your coach should have a TOW/HAUL mode and if you're towing your Jeep, you should be in that mode all the time. As stated your coach will downshift, but often it will do it a little late. As many become more comfortable with driving their coach and know what it can do (performance wise) they elect to manually shift a little sooner.

On my coach, as soon as I reach the base of the grade, I downshift from 6th to 5th, knowing that is where I'll have more power. I may have to shift one more time to keep up my speed.

Your TOW/HAUL mode is also used to slow you down when descending a hill. I know you've already been chastised for the speed, but I could see how a new owner could quickly find themselves moving down a grade too quickly. As others have stated, your coach tires are only rated to 75 mph, which means they will work at higher speeds for short bursts, but are not designed to be driven that fast. At 80 mph or even 70-75 mph, when towing, things can go wrong very quickly.

Am I the only one who caught this? Made me laugh! I'm still smiling! Everyone else complaining that you should never go 80mph. Thanks, you brightened my day!

My coach seems to love 75+ mph. I on the other hand keep picturing that red MH passing the semi when it blew a front tire a couple months ago and wound up going through the median and into oncoming traffic! 62MPH for me it is. Sometimes up to 65 but this beast loves to run if I don't use the cruise.

I have been advised by long time class A owners if the hill is just a steep going down as going up you should do them both at the same speed to maintain control going down.. I found it good advice..

We will be using the tow. He said he didn't have it on.
And 60 mph is our cruise speed from here on out.

If you will be going into California, the speed limit there is 55 mph for any vehicle towing anything. The Highway Petrol might give a little leeway up to 62 mph, but then again they might not. A 5 mile over limit ticket costs about $300 with the fees added on. I generally chance it and set the cruise control at 59.

Not headed to Cali this trip. Thanks for the info. Current posted speed limit is 75mph.
Guess I'll pull out the manual curious as to what it says.

Ok let me state WE did not intentionally drive at 80mph downhill. And our normal quick trips have been in areas that are 55 mph limits no mountains. WOW... No where have I read you should drive at 60 to 65 mph for safety issues. I have read I get my best gas mileage when cruising at 60 mph. Posted speed limits where we are at on this vacation is 75mph. We do obey the speed limits posted.

I am very thankful to all that have given me very good information. I want to get to my vacation destination safely. SO thank you for taking the time to answer my question and help us be safer RV drivers.

My coach will run all day long at 75-80 mph BUT why would I want to do that??? Major safety issue; really cuts down on mpg; and most importantly we travel to see the scenery.... Hard to see it as its whizzing by at 80 mph.....
