The install started at 7:00am on Wednesday in Davenport, IA at Interstate power. There the Allison transmission needed to be coded to send a signal when road speed hit approx 8 MPH. This signal is used by the new computer HWH installs. This process took all of 10 minutes, and I made the short drive to HWH headquarters in Moscow, IA.
My plan was to get the Air leveling system, which allows leveling the coach using either Air or Hydraulic, one or the other, not both. Air leveling has a lot of draw to me, allowing the leveling of the coach on softer grounds without the worry of digging in.
The installation was to take 2 days, so I planned on staying in the coach. They put the coach in their heated garage, on a 5 ft. platform. I had electric, and could open the slides. Perfect setup. They gave me a set of keys so that I could come and go, and offered to let me act like I owned the place. I cannot say enough good things about the company.
I left to do some shopping, letting them work. About an hour after I left, I got a phone call from Paul, the owner of HWH. He asked if I had ever heard of Active Air, which I had, and if I would consider upgrading to that. After answering a few questions, and getting more information about what the system does, I agreed. This meant that the install was going to take 5 days, but in the end I was going to have a very advanced system.
The final result is truly amazing. On the test drive, I decided to see if this 43 foot motorhome could handle the 25MPH corner @ 25MPh, vs. the normal 15. The answer is YES…There was NO LEANING, and no loss of weight distribution.
This next part will cause HWH some problems unless I make it very clear – THIS IS NOT ENDORSED NOR RECOMMENDED BY HWH. THIS IS SOMETHING I DID ON MY OWN FREE WILL. Hopefully that clears up the legal issues.
I took the same corner at 45MPH. Crazy? Yes! Stupid, Yes! I don’t recommend this as an option to drive a motorhome like I drive my BMW, but let me tell you…the coach handled it. What did not was my Residential refrigerator, because I forgot to lock the doors! Lucky for me, HWH’s Engineer, Mitch, was in the coach, and was able to pick up the mayo & butter, so I could try some quick lane shifts. I did a simulated emergency lane change…AND IT WAS SO MUCH FUN…I was giggling.
I don’t think I will ever drive this that way, but there are other things that are of big benefit, and the company actually mentions these on the website.
Sharp turns, the coach doesn’t rock. Going down the highway with a big side wind, the coach doesn’t rock or lean.
In fact, with comfort steer, Active Air, and a Tag axle, I drove 200 miles in a 30MPH wind gusts, and never knew it. My first sign of wind was when I stopped at a Pilot to get fuel. When I opened the door, it almost came off its hinges, the wind was so strong! Up to that point I did not know that there was wind!
Leveling the coach is so easy with the Air level system. I chose to use Air the first night, because the temps were below 18F, and the jacks would be very slow to retract in the morning. Also, they had accumulated a lot of ice. Another good reason to have the air option.
I will post more after I have had some time with the system. Please feel free to post comments or ask questions.
