I take it that you don't have the 5 Star.

The Ford V-10 is a high revving sweetie. She thrives on high RPM and will do the job every time. As for losing momentum on a hill, (any engine will struggle until the optimum RPM is reached again). That is what I hate about truckers using both lanes in the mountains of Tennessee. They can't pass each other and cause you to loose momentum. Bummer!!

For us personally, the Class C suits us perfectly. We tow a Jeep Wrangler all 4 down(3600 lbs) and don't even know it's back there. I would highly recommend you research a tire pressure monitor system and invest in the system that you're most comfortable with. Hope to see you around the campfire.

I have the 5-Star program on my 2008 E-450 Ford powered Winnie 31C... I tow a 2008 Wrangler 4 down. Before the 5-Star I constantly hit the 4000-4200 RPM range when pulling even moderate hills. Since the addition of the 5-Star driving the same hills I don't hit those high ranges as soon nor for the long durations. My experience with the 5-Star is it works.

I had taken a slight hit to gas mileage when I started towing the wrangler. I got some of that back on long hauls. The engine does not seem to work as hard either. I am one who's experience with the addition of the 5-Star has been positive and would do it again.

About the same as turning the tow/haul mode off?

We have a five star tune in our Newmar and I would hate to part with it. I tow with a GVWR of about 25K with a max of 26K. I usually turn the cruse off in the hills, as that helps a lot with the high RPMs. And I run with the tow haul on most all the time as it helps any time with slowing down and does wonders in the mountains. Our dealer only sales Jayco and Newmar, I wanted a Jayco but after looking at the Newmar class As, just couldn't do it. If I ever buy another Jayco, which was our first RV in 1994, it will be an Entagra!

Yes and no. With the "tow/haul" mode the trans only uses 4 speeds instead of 5. The 5-Star adds the 5th speed into the equation. Thus changing the shift timing and keeping the RPM's lower. It also changes the shift sequences when the "tow/haul" is off. The overdrive stays engaged longer without the high rev kicking in at 3rd gear and RPM's kicking up to 4,000+. Goes into 4th at around 3,200-3,500 instead. This saves gas on those long steep climbs as well as the moderate rolling hills.

It also allows me to use cruise more even in the hills. I was not a believer until I used it. Have over 9,000 miles with it and there is a huge difference over the prior 8,000 miles.

We have the 2012 and the high RPMs really took getting used to. Towing something small winds it up a little more but it can handle it. I rarely drive over 60 though which also takes getting used to as speed limits in the southeast are usually 70 so I normally drive around 80. Over 60 in the RV just feels reckless.

Pretty sure you can still get to O.D. with tow/ haul engaged.

Ford programmed their 3v V10 trans to only use 4 gears when "tow/haul" engaged. They dropped the overdrive from the programming. Before installing the 5-Star I took my coach to the dealer because I noticed this and thought there was an issue with my trans. It was explained to me this was normal. The 2v V10 does not have the tow/haul option and uses all gears.

I further researched this and if you look at the spec sheet for the shift sequence of the 3v V10 you too can see the difference and the missing 5th gear OD in the tow/haul mode.

5-Star corrected this for me and made a world of difference. The 5-Star works for me. I travel down the road at 60-62 mph and here in the west I am in the mountains a lot. My travels are much smoother with the 5-Star.

I have a 2012 E-450 with tow/haul and I am pretty sure O.D. works when engaged.

Look again. Ford's "tow/haul" mode is what most manufactures call "overdrive off". But hey if yours still had overdrive when in "tow/haul" mode you got yourself a great set up.
