Over cockpit bed

My Challenger cockpit bed lowering mechanism came down unevenly, driver side ahead and then passenger caught up when I continued to depress the down button. Now I want to raise it and both sides start, but the driver side stops after about an inch and the passenger keeps going. Of course I stopped it and reversed as soon as it got out of sync.

I have some slide out silicone lube, but wasnít sure I should put it on a vertical track. At least I am at home and not stuck at a campground!Any advice would be appreciated.

Should be an easy fix. Raise and lower the bunk a couple of times making sure you hold the switch down for about 5 seconds after bunk stops its travel. This has the effect of retiming the motors. THEN make sure you use the pins and that the bed is locked down on pins - that is done by raising the bed, inserting the pins and then lowering the bed slightly back onto the pins.

Most times you issue shows up the pins are not in place during travel. I know - I had it happen to me and I had had it so cattywampus I had to manual lift the bunk back up into position - then I retimed it. I call this little mishaps - knowledge knots.

I pushed it up as I held the button and it went up. Should I use the silicone spray on the track to help it out?

I don't believe the silicone spray is needed but I also don't believe it will hurt. The most important thing is to retime the motors and to use the pins.

Yep - I always use 'em now. In the past I've had the pins fall out of one side or the other and found the bed cattywampus.

Hope you're enjoying your coach and are having safe travels.

So far Iíve only made a couple of overnight trips. Now that itís warmed up Iím trying to get it outfitted for some substantial travel. Iím concerned that my mileage has been 4.5 mpg. Is it normal to be that low when the engine is new? I donít have 1,000 miles on it yet, so I have not tried to tow.

The lube is not necessary on the track just the motor couple times a year.

Yes there are several videos on how to lube the motor.

We have the 37LX model, and live in AZ so it had about 2,000 miles already at the dealer. So I donít know about sub-1k gas mileage. We have been getting about 8 mpg on our first few trips.

You might want to look into some of the stuff offered by Banks...
My Dad's Holiday Rambler Class A was getting 4 mpg.
He had the Banks kit installed, and it jumped up to almost 8 mpg!
With LOADS of more power!

Not sure I can talk the hubby into another major ďinvestment ď in the coach right now☹️. I was sure expecting 7-8 mpg. Maybe I will give Ford a call about that and see what they say. Thanks!

8 MPG sure isn't encouraging. I have 240 miles and haven't taken it out yet. Waiting on weather change. Hopefully in the next few weeks.

Mothertype55 - 4.5MPG is WAY low!! We move on down the highway towing a 4500 lb Ford Explorer. When I watching the mileage it was routinely running about 6.7 mpg. I quit paying much attention to the MPG and I look for the DTE number - generally around 490 miles after fill up. Lots of things contribute to your 4.5 mpg number but don't worry much about it until you've gotten a couple of days traveling. At 4.5 mpg your DTE after a fill up is somewhere around 350 miles. I absolutely don't believe that is correct.

If you're not towing 7 - 7.4 should be a good number.

I will be towing a CRV, but havenít been yet as I am just hitting 1,000 miles. Just been doing overnighters locally and my daughter has driven her car, so havenít needed my own wheels.

I hope youíre right about the 6.7mpg! My daughter and family are moving to be near her sister in the Bay Area, and we are planning a caravan from Knoxville the end of May. We will probably detour through Texas to visit family on the way, so itís looking like 3200+ miles. I had planned my budget on 7 mpg, so 4.5 almost doubles my gas cost.

At least while all the grands are in one spot I will be able to store the coach out west and do trips with them without driving long distances cross country.

The winter freezes really did a number on the roads here...potholes everywhere! The whole coach shakes and makes crashing noises when we hit irregular pavement. Would Sumo shocks make the ride smoother?

Thanks for the help!

Mothertype55 - 4.5 won't be close unless you're losing fuel somewhere in the system. Given the terrain along your routes from Tn to Ca via Tx and with your CRV toad - 6.7 should be doable. Especially if you run a bit slower than we probably do - our comfort speed is 67 MPG. Once you hit Ca, your max posted speed will be 55 MPH. Show see an upward tick in your mph. Your planning 7 MPG is probably on the optimistic side but close especially if your speed is more like 60 MPH.

And oh yeah - be safe and blessings as you prepare.

A lot of the fuel mileage answers actually come from the dance that your right foot does on the "loud pedal".
Try slowing down a bit, and see what happens.

We have a 37' 2018 Miramar and the worst MPG I've had so far was 6.5MPG towing a 4 door Wrangler. I was driving faster than I normally do on that trip (70-75mph). The best MPG I have gotten so far was 8.1MPG and that was running about 62-65MPH also towing the jeep. I received the motorhome with 1100 miles so the engine might just need to loosen up a bit after breakin.

Maybe once I am getting more ďhighwayĒ miles vs ďin townĒ miles it will improve. Thanks!
