That Big Giant Mud Flap

I'm going to remove the mud flap. I can't see any real benefit. I didn't have one on my last MH and there were no problems with rock damage to my Jeep. I have also noticed the sun being reflected by the chrome trim on others while driving and our travelling companions on the last trip said ours is causing the same problem.

Has anybody else removed theirs? Any reason to keep it on?

Just curious.

I'm thinking the same, but just haven't made up my mind. I believe what other posters are saying that it throws up more than it doesn't.

I removed the one on the new to us '03 we bought about a year ago. The rubber flaps behind the duallies provide ample protection.
I listed it here in the Classifieds and it sold for $250 plus shipping.

There have been a few threads on this. I took mine off after it warped and found that my toad was much cleaner. I wouldn't run one again, no matter how cool it looked.

I recently took mine off, cut about 2" off the thing so it wouldn't drag when I lift the tag or drive over dips in the road. I have pondered removing it but will see how it goes now that it is shorter.

We did get some small rock chips in the toad when we drove for about 20 miles over a freshly resurfaced road (tar and chip) in Oregon. I don't know if the big flap contributed to that or if it prevented it from being worse.

Mine had a full length rear flap when we bought it, the engine compartment was always really dirty, After reading up on this, I cut the flap down to 12" , engine compartment stays a lot cleaner now, plus with the short flap, it works great with our Protect-a Tow.

I removed our mud flap a month ago for a different reason – to eliminate “jacks down” alarms. We had experienced frequent alarms, always from the left rear jack, always after about 30 to 45 minutes' driving from a cold start. Another Alpine owner suggested it was due to heat build-up from the exhaust, turbo & radiators all together near the left rear jack. I researched HWH manuals and found this statement: “HWH uses a simple rule; there should be no direct line of sight from any HWH component to a heat source.” Somehow WRV ignored this rule when building our Alpine. Since removing the mud flap we have had only one jacks down alarm in 9 driving days.

Ours is a large mud flap mounted rigidly to the frame. I had considered cutting a few inches off the bottom, and perhaps mounting it on chains to allow more air flow. But since several posters on this thread mention other benefits, like a cleaner engine compartment, and no increased damage to toads, I think I’ll leave mine off.

Mine came off years ago 'accidentally' and I never re-installed it. Don't really miss it...

The most common reason for false "Jacks Down" alarms is operator error. When you put the jacks in the "Store" position, DO NOT turn of the HWH controller. Once the jacks reach the store position, the controller holds the solenoid valves open for up to six minutes to allow all of the fluid to return to the reservoir. If you turn off the controller, the valves go to the closed position. If any fluid is trapped in the system, once it heats up it expands and the ram on the jack moves down slightly. Since I've learned about this, I haven't had a false alarm - before I knew about this I turned my HWH system off once the jacks showed "store" and I had false alarms.

Mike,I have had a jack down alarm.When do you shut off the HWH controller or what procedure do you use when preparing to travel?

Hi JIm

If you do nothing with the HWH control panel it will time out and shut itself down after 6 minutes so no need to worry about timing!

Mike is correct. We had the HWH jacks on our previous coach and if you do not wait for the system to shut itself off (takes several minutes), ambient heat will expand the fluid trapped in a jack/s and give you a 'jacks down' alarm. More likely to occur in hot weather, of course.

I always pressed the store button and went outside and finished up putting things away. Sometimes it took 5 - 6 minutes or more to fully retract the jacks and shut itself down.

I've noticed that if you start the engine when the jacks are in transit, silverleaf reports with "system not responding" so I either do another store command or wait to start until the jacks are fully stored.
