Rear mud flap
« on: May 27, 2018, 08:59:27 PM »
Questions:  Has anybody removed there rear mud flap for any length of time?
                   Having it removed does, it increase fuel mileage?
                   We have a road master shield that we have used for years, the bottom of the toad has some sand pit spots.
                   It seams to drag in campgrounds, streets,  The coach is level going down hwy. and has 3" of clearance before leveling
                   Any input would be appreciated.

Dale,

We had an 06 Monterey. Back in 09, I wired our rear flap up so that it was held out of the way.  Doing so helped to reduce the engine temp while on the road, almost completely eliminated all the gravel that we found on the toad at the end of the day.  The mud flap often bounced on the road which would kick all sorts of gravel, etc. There may have been a slight increase in miles per gallon, but nothing significant.

We replaced ours 3 times because it was bending in the middle from the hitch backing up. On nasty wet days I was to lazy or to cozy inside to go outside and secure it up out of the way. When the third bent I cut off the letters A and V now it was a B E E R coach. But it still drug the ground so I removed all traces of the mud flap. Better engine cooling and haven't noticed as many rock chips. When and if you remove it have someone help as it is pretty heavy.

I took another route - I removed the “Beaver” plate and the accompanying backup plate, then filled all the holes with black plastic push-in trim plugs. I then took the entire flap off its hard mounts, replaced the top steel rail and added chain link hangers so it could flex as need be on the road or when it bottoms out in some leveling situations. Removing the plates allows it to buckle if need be and the flexible hangers allow for some upward travel as well if it does bottom out when leveling.

It sounds like many of you have flaps on the ground or inches from the ground. Mine is about 4 or 6 inches off the ground. In the photo the flap is at normal ride height. Is this about the same as yours?

I had the flap off for a while while installing my motorcycle carrier, and one day my wife driving her car behind me and said there was a lot of dust and stone getting kicked up without the flap installed.

Thanks for all the input.  I have had it off to repair, It does not cooperate well with others, I will remove it for the remaining of the year and check. Jim, your two people team is spot on.

Our mudguard was pretty beat up from dragging under our relatively low-slung coach as we crossed the sidewalk dip to our driveway.  One year I finally removed it, put it across a couple sawhorses in the backyard, used ballpeens and other devices to straighten it, and painted damaged rusty spots with POR-15.  I couldn’t do a whole lot with the scratched chrome, but overall it sure looked better and remains so.

After listening too many times to Lee screaming at me as the thing drug across the concrete, or got caught between driveway and hitch, nowadays upon arriving home I unhitch the car and crawl under to remove the mudguard.  It stores nicely out of harms way in the garage on the floor under the pickup.  When we leave for a trip, I spray some dry silicone on the clevis pin threads and remount the flap after driving the coach out on the street, and then hitch the toad. 

Yeah the thing is heavy and clumsy for one old guy to maneuver under there, but I still believe it keeps a lot of bouncing stuff from the toad front, and is worth the 8-10 mins effort.  Yet it’s not a solve-all, for sure.  The toad suffered a lot of grit damage the first year until I added a Roadmaster Guardian that had a noticeable effect.  One could also add the Roadmaster under-hitch screen as well, but I’ll only do that if we ever afford a new pristine toad.

It has occurred to me to remove a chain link from the mudguard or insert the clevis one link higher, to lessen it’s dragging events, but stopping ricocheting pebbles to me is more important, and the lower the better.  A beat up guard is better than a beat up toad.  It’s hard to imagine a worthwhile mileage change without the mudguard, and a properly functioning and maintained engine should run at optimal temperatures regardless. 

Just one fellow’s opinion among diverse others’.
