RE: Magnum MS 2812 Charger/Inverter Issue
why do I still get power to my non-inverter circuits such as washer/dryer and AIr Conditioners?
Do you have power to these all the time when on shore power? Or only initially?
Like I said, on mine, the hot relay shorted - essentially the hot leads from the shore power were connected to the hot leads from the generator power.
When power is applied from the generator side, the delay is initiated then the neutral relay switches over to the generator neutral - everything is happy and works.
When power is applied from the shore side, the delay is initiated then the neutral relay switches over to the generator neutral - now the hot and neutral is not matched and the problem occurs. All power is lost and the inverter thinks it's not connected to anything and turns on supplying power from the batteries. When it does this, the neutral relay drops back to shore neutral and now there is matched power in the hot and neutral supplies starting the cycle again.
This may not be what is happening in your case, but if you notice the inverter/charger continually cycling, I bet it's something similar.
If you know where your transfer switch is, open the cover and inspect the relays, you'll notice signs of overheating if this is your problem.

RE: Magnum MS 2812 Charger/Inverter Issue
Most likely the hot relay in the transfer switch. I just had to replace mine, very similar situation - when plugging into shore power, I had power for 30 seconds, then lost it.
In my transfer switch, there is a 30 second delay in the neutral relay to give the generator to come up to speed before transferring the full load. The hot relay was shorted so when applying shore power, it triggered the 30 sec delay. During this delay, everything worked, but as soon as the neutral relay switched, shore power was lost.
Replaced the relay and all is good now.

RE: Help-can't get Tully into the car due to size-RESOLVED
Is there some reason the dog can't jump in on it's own?
My 60 lb dog took a few times for him to understand what he needed to do, but now I just have to open the door, give him the command, and he jumps in.

RE: 2015 Ford Focus flat tow damage
My buddy had his replaced at 30k miles. and has been flawless for 100k miles. just a month ago he needed to have the shift module replaced. still under the extended trans warranty. all these transmissions are, are a manual transmission with a complex shift assembly attached to them.
Correct, but the "complex shift assembly" was notorious. I had mine for about 60k miles, and while mine never "failed," it did a lousy job of shifting. I took it in to two different dealers, they just said "it's normal" and wouldn't do anything.
Clunks, stutters, hard shifts...no fun to drive, and I always worried about it leaving me along the side the road.
Never so happy to get rid of a car as I was with that one!
The story I heard was that this transmission was modelled after a BMW or Porche (not certain of the brand) that worked really well. I'd guess the Ford engineers missed a few fine details when copying it, or just cheaped out on something, that resulted in a terrible user experience.

RE: 2015 Ford Focus flat tow damage
I think Ford would be responsible only if the baseplate was designed and supplied by Ford. As an engineer myself, it's hard to predict what an end user might do - that I need to design around. Top be absurd, should Ford design the hood hinge bolts to handle being flat towed if someone wanted to pull the car with suction cups on the hood?!?!
I'm afraid the flat tow "endorsement" from Ford was probably geared towards the transmission only. The actual method of connecting the car was outside their design parameters.
For example, when I installed my Blue Ox baseplate, for each side, I used some existing holes, but I had to drill a big one to get the nuts into the rail. I seriously doubt the existing holes were placed there by Ford for this purpose, I could be wrong though. Certainly, they didn't design for the big hole that had to be drilled.
What would be interesting to know is whether there was any interaction between Ford and Roadmaster (or BlueOx, or any other baseplate manufacturer) when Roadmaster designed the baseplate, or whether Ford provides any design criteria for attaching parts to the vehicle. In addition to the baseplate, I installed a receiver hitch on the back to carry bikes. From what I remember, it used existing holes as well.
I'm in a different industry altogether, so I could be way off base here!

RE: 2015 Ford Focus flat tow damage
That's pretty bad! I'm glad you were moving slowly, that would have been bad if you were on the highway!
Some interesting things I can see in the photos:
Photo 1 - the welds are all still intact to the connection plate.
Photo 2 - The frame tube is where the failure occurred. It looks like there might be some rust at some of the fracture locations, indicating a long term fatigue failure.
This tells me it was probably not a manufacturing defect, rather a design problem. Not necessarily a Ford design problem, just that the member sizes weren't adequate for the added stress of being towed.
On the other hand, Ford states that it CAN be flat towed. I suspect that they didn't have a full grasp of the stresses involved. If memory serves me correctly, 2015 was the first or second year the Focus was flat towable.
Anyway, sorry this happened to you, hopefully others can learn from it. Sure makes me glad I got rid of mine a few years back!

RE: 2015 Ford Focus flat tow damage
I used to have a 2015 Focus that I flat towed. I installed the base plate myself so I'm pretty familiar with the front of the car.
I don't know exactly what happened to the OP, but I surmise from his description that the frame broke rearwards of the base frame attachment point.
Like many base plates, it is attached with 6 bolts - 3 on each side. Additionally, the base plate is connected to the frame via two cables - not the safety cables between the car and coach. On the focus, those "internal" cables also attach to the frame, so if the frame gave way, the cables would go with it.
Hopefully there was an aux brake system that stopped the car after it came loose.
Having said all of that, I can't imagine Ford, or any other manufacturer for that matter, repairing something like that, warranty or not - even a frame that is just bent, results in a total write off.

RE: Need help - Weight distribution hitch installation pics
I don't know anything about that particular hitch, but based on your description and the measurements you posted, I think you need more tension on the spring bars.
The fact that your front fender measurement with the W/D hooked up is still higher than with no trailer means you're not transferring enough up to the steer tires.
Back when I had a TT, I adjusted it so my front measurement was the same if not a slight bit lower than when un-hooked.
This is good for ball-parking it, but as others will probably add shortly, you should get to a scale to see what is really happening.
If this system is anything like mine was, the more spring force there was, the more sway control it provided.

RE: water heater works fine - IF- I leave door open
My guess is the airflow mixture/regulator needs to be adjusted to get more airflow into the burner. Have you travelled to a higher elevation than you are normally at?

RE: Fish bowl cooling class A
I have always had a problem cooling and heating the fish bowl on my RV.
The dash air has never cooled the fish bowl and the front air does not send enough air while driving to the front.
I’ve tried directing the flow to the front, using a fan to push the cool air to the front, nothing works.
Also I do drive mostly out west with temps over 90 many times.
So has anyone done any creative ac mods to help this situation ?
Like replacing the dash ac system and putting in something that works, or adding some type of stand alone ac unit in the front ?
Let me know

Having a very similar coach as you, I face the exact same problem. Hot in the summer, cold in the winter. In the winter, I can feel the cold air, in the summer, it's just generally hot. I suspect air leaking in from outside but I haven't been able to pinpoint where it's coming from. I even put a fog machine in the generator bay while parked looking to see where the air came in, with no luck.
In the summer, I've had the most success opening the louvers on the front air so most of the air blows straight down, and a fan a few feet behind that blowing forward. Certainly not cold up front, but made it a little more tolerable. My bigger problem is keeping the engine from overheating in those conditions!
I recently got a thermal camera and will be using it on my next trip to try and see where the air is coming in from - I suspect it might be around the stair well. It will probably be more revealing in the winter, but I'll try it anyway. If I come up with anything useful, I'll follow up here.
Forgot to mention - I had the dash air serviced a few years ago, it seemed to help in the sub 90 temps, but didn't make a difference above 90. The next year, it didn't seem to make much difference at any temp, and I'm not about to spend $500 or $600 each year for a marginal improvement.

RE: Towing with Auto Leveling
As mentioned before, the purpose of the weight distribution is to put weight back on the steer axle. The only way you can effectively do this is to use a scale. Just looking at whether or not the truck is level is not a good indication. After you've got the weight shifted to the steer axle, you'll probably only have a very slight "out of level" on the truck.

RE: Park suggestions/opinions in or near San Jose, CA.
I've stayed at Coyote Valley RV several times while working in Cupertino. It was always well kept and clean and quiet. Far enough away from the "big city" but close to all the grocery and shopping stores in Morgan Hill. I'll stay there again next time I need to be in the area.

RE: backing up 4 down jeep jk
As far as I understand, the issue with backing is the steering wheel going one way while you want the vehicle to go the other way. I've seen people get around this by using a heavy bungee strap through the steering wheel attached to the brake pedal (only when backing up, not when moving forward).
I've backed up a few feet also with no ill effects.
I find it hard to believe that backing up a few feet would hurt he transmission/transfer case and the note about towing backwards means just what it says - don't TOW it backwards.
Furthermore, it backing it up a few feet really caused damage, I would certainly expect to have heard about it somewhere. To the contrary, seems like a lot of people have said they back up a few feet when absolutely necessary without any damage.
Just my two cents...

RE: Used Tow Bar Values
I don't know how anyone gets their tow bar "inspected" or rebuilt or repaired. I have a Blue Ox that I have attempted to have looked at but Blue Ox NEVER responds to email.
Interesting, mine is also a Blue Ox. I've not tried to get it checked out, but was thinking about trying this summer.
