I have 5 star on my 2012 V-10 class A. I also had it on my 02 V-10 Excursion. Made a huge improvement in both. The shifting alone was well worth the investment! I gained .5 mpg on my Excursion and .3 on my MH. I mainly got the tuner for the MH to do away with the horribly intrusive drive by wire that would pull throttle on you when you needed it the most. 5 star still leaves some “safety” in there but it’s far better. And the shifting is much improved! You do get some extra HP but it’s not much and really isn’t needed once the drive by wire is taken care of.
Just about every MH should be run in Tow/Haul. The reason is the chassis is always loaded. I really wish they would make it so the T/H default was on instead of off. Might be good for an empty bread truck or cargo van, but not on an always loaded RV.

I had an '08 F250 with a 5 Star tune. Small increase in power, but the biggest benefit was the shift strategy they did for me and later for others. Stock it would shift into OD any time you let off the throttle for a second or two. Really annoying. Mike set mine up so that in TH it would not shift into OD until about 65 mph. Since I seldom towed that fast it stayed in direct, where it needed to be when towing heavy. I probably would have traded the rig off if not for that tune. Could not stand towing with it stock.

I think I will just try using TOW Haul Mode for my next long trip. Thanks for response

Hello, I have a 2014 Bounder and was considering the 5 Star tuning. While I understand many will have different opinions, I don't expect any material fuel efficiency, rather I was hoping for better shifting especially up hill. I also watched a video online that tested the 5 Star tuning and it was done with vehicle in "tow mode" without an active tow. Would this change the 5 Star tuning function? Would I benefit having my Bounder in tow mode even when not towing a vehicle or small utility trailer? Anyone install 5 Star on the Ford V10? Love to hear feedback.
Thanks
Your Bounder is very heavy to start with so absolutely yes, by all means enable the Tow/Haul mode.
Ford's Tow/Haul mode enables automatic hill descent downshifting (saves you from manually needing to downshift when going down hills and if you feel the need to downshift further just press on the brake pedal then let off after it downshifts).
Tow/Haul mode automatically adjusts the shifting strategy for hauling and towing heavy loads (being you are in a heavy motorhome this is what you want). The shifting strategy will change shiftpoints to take better advantage of the engines HP/TQ which may include holding out upshift a bit longer.
As far as tuners, well 5Star is trying to sell you on the idea that you "need" their product, it is a "crummy commercial" and treat it as such.
Their tuner will further adjust shift points strategy and shifting pressures within the transmission. This may add additional stresses to your transmission that were not accounted for by the vehicle manufacturer so it is a "Buyer Be Aware" type of thing. Roll the dice and take your chances..
Would I add a tuner to any of my vehicles?
Nope..
You have a non turbo gas powered MH, treat it as such and it will live a long life.. Hop it up, and you run the risk of shortening the life of your rig.
Try using the Tow/Haul mode everytime you start your MH before dumping money into a tuner.
