RE: Water pump sucking air
Does the tank have a gravity fill port on the outside or is it pressure filled from the water hookup point? If it's pressure filled from the water hookup point are you sure water is making it to the tank?
If gravity fill does water come out the vent hose when full? Or does it only spit water back out around the hose?
Gravity fill port outside the TT.
I fill it until it is right full, and coming back out the fill port.
100% for sure the tank was full to the top.

RE: Water pump sucking air
Thanks for the input guys,
It was a while ago now this happened - I've been so darned busy that I have done nothing to the TT in a long time. Years. Shame on me.
I've made sure I have access to city water the past few times out.
The pipe from the tank to the pump is rigid, and although it easily lifts up out of the floor, I've not tried pulling it right out. I figure it should not be loose like that, it should be tight and sealed so water doesn't splash out the top of the tank.
Don, I do suspect something in the pickup tube in the tank. Wish I didn't have to drop the tank to get in there, but it's the only way. I have a borescope. I wonder if I could somehow sneak it in there, perhaps down the filler neck. Never thought about that until right now.
Thanks for your list John, I've never been in there, no idea if it has a strainer. I'd have to pull it apart. Valves? It was working,then stopped. Don't think any valves were turned during the time. Hole in pump inlet line? That is possible and worth checking. Pump is good, as it pressurizes with a hose in a bucket. Tank was full to the top, so that wasn't an issue. And it isn't running out the bottom.
Lantley, I could try to pull the line out of the tank and stick another in there, but I still concern myself with the apparent lack of seal there. It should be tight into the tank. I shouldn't be able to lift it up and down with ease.
I'll try to find the time to pull it apart in the storage yard to see if I can learn more about the cause.
Thanks all. :)

RE: Water pump sucking air
Thanks for the replies, but as mentioned, the problem is in the tank between the pump and the pickup in the tank.
The pump is fine as I outlined above.

Water pump sucking air
I have a bit of a head scratcher with my TT.
Suddenly one day my water pump started just running on. It runs steady and only a little water spurts and sputters out of any tap. It appears to be sucking air.
It does this with a full fresh water tank. It's not the pump, the problem is on the pickup side in the tank. When I disconnect the tank pick up at the pump and put my winterizing hose on, and put the hose in a jug of water, it pressurizes and the pump stops running.
The feed pipe out of the tank goes straight down into the tank through the floor from under my bathroom sink, right close to the pump. I noticed that I can take that pipe and easily lift it up a long ways and down in the floor. That should not be happening. It seems something has broken off / come loose in the tank.
I'm not 100% sure what it looks like inside the tank for the properly functioning water pickup. I've never had the need to take one apart... until now.
I'm assuming I'll have to drop the tank and see if I can get in there to determine if something came apart.
As long as I'm on city water, all is well.
Any thoughts?
Thanks.

RE: Install "Generic / Text Only" printer on port
Can you possibly do a workaround by selecting Microsoft Print to PDF as your printer? This will invoke the Windows save to PDF menu.
Then you have a digital copy of it which can be printed from anything, anywhere, as Adobe Reader is free and works with any PDF document, allowing you to physically print to paper from any printer.

RE: Replacing Water Heater
I did a repair on a friends 5'ver a number of years back. He had a 10 gallon tank that died in a CG we were both staying in. He bought a new unit at the local RV place and I swapped it out for him.
The tank itself was ok, so I kept it, thinking I would repair it an swap mine out, going from 6 to 10. I wish it was that easy.
As mentioned, physical size difference.
For obvious reasons, the 10 is bigger. It requires a bigger opening to fit in. This requires surgery on the wall of the RV to provide solid framing all around to screw the unit in.
On mine, I didn't have enough extra width and height to make it an easy conversion. I would have had to carve up a partition, do cosmetic repairs and more, so I scrapoed the idea.
However, if you have enough extra width and height inside, and you're willing to enlarge the opening of the outside wall, yes it is doable.

RE: RV style AC attic duct work - what is it called, brand etc
The foam board I mentioned has foil on one side, kraft paper or similar on the other.
It is typically available at suppliers of home finishing materials, such as siding, roofing, insulation and the like.
I'd forget the big box stores such as Lowes, Home depot. They cater to the home handyman more than the tradesman.
In Canada, there is Kaycan, Gentek, Mitten Vinyl, Monarch, Royal and a bunch more. This is the best source for these kinds of materials, but only if it's the product geared towards renovation siding etc.
The V cuts in your pic work for folds, but difficult to achieve. Using and aluminum brake with gentle clamping pressure will work just fine.

RE: RV style AC attic duct work - what is it called, brand etc
John, I can't directly answer the question for sourcing the original product, but I could offer a suggestion for fabbing your own.
There is a construction product called Fome-Cor. I used to use it extensively years ago when I was doing reno siding on old homes. It is a quarter inch thick foam with perforated foil on one side, kraft paper on the other. 4 feet wide by 50 feet long, and it comes in a 2 foot increment fanfold.
If you have access to an aluminum brake, like the 12' 6" one I carry on my work truck, you could cut this product to size, run it through the brake and create your own duct. One side would have an overlapping flap that gets taped together with foil or duct tape.
It would be flexible enough to sideways flex it to a trapezoid shape so it could be flexed to insert into the narrow opening of the trusses, then returned to a rectangle shape. You could further insert rigid foam blocks on each side, at the trusses, to help it retain its shape.
I know I could do this as described, but you need a brake to do the folds. The brake has to have a gradual cam lock system to put gentle pressure on the foam board, not a snap lock system which would crush it.
Just thinking out loud with this idea, I have always been one to create my own things when none are available...

RE: Why not jack trailer under the spring plates?
I always jack under the spring plates and never give it a second thought.
I usually use a squat bottle jack, take it up far enough to get the wheel off, done.
All this hooplah about it'll bend your axel, bend your frame, wreck this wreck that.... Horse Puckey!
Consider how much any RV flexes, bends, heaves and dips on the roads we drive on. It's a hundred times more than lifting an axel a couple inches.
Take it to a tire store and watch how they jack it. Under the spring plates...

RE: Rear Picture Window Glass Removal
There are different styles of frames with different methods of holding the glass in.
My TT for example, has a rubber reveal molding on the outside of the window frame. It locks into place with a pressure fit into a notch in the frame provided for that purpose.
To take the glass out, the rubber strip is removed, exposing the edge of the glass. There is an adhesive glazing tape or similar holding the glass to the frame. This has to be cut with a utility knife blade from the inside, releasing the glass. Then the glass comes out to the outside.
This is my TT. Others will vary.
Best to look for a reveal molding that comes out somewhere.
If you can post some pictures here that would help ID the style of window you have, so we can offer input.

RE: Camp light from Aliexpress - don't!
Do you have any cordless power tools - what ever brand name?
I run Dewalt, so I already have a fleet of batteries and chargers. I bought the flashlight, tool only for 30 bucks. Bought 3 of them actually, 1 for the RV.
Works great.
Perhaps you could do the same if you have cordless stuff already.

RE: ALWAYS something!
Yes, always something....
I attended a wedding in BC over the Labor Day weekend.
Hadn't had the TT out yet this year.
Brought it home, dewinterized, usual stuff. Filled the fresh water tank, ran the pump to fill the HWT and flush the lines.....
The pump runs on and on and wont shut off. It worked enough to do the task at hand, but rather weakly. Hmmmm.
Long story short after investigation, pump is sucking air from the tank side. It still pulls water, but the cold taps sputter and spit, the hot doesnt. I can pull the feed pipe up and down where it goes through the floor into the tank. That shouldn't be happening.
Looks like I have to drop the tank to figure out what came apart...
At least I had full hookups for the 4 nights out, didn't need the tank water.
Sighhhh.... Always something. :R

RE: Looking for slide out insulation, 1 1/2"
Consider rigid insulation such as SM or similar. It is available in various thicknesses including 1 1/2".
Cut to fit the voids, and for any gaps or going around wiring etc, use a bit of expandable spray foam.
Super light weight and it has an R value of R5 per inch, so R7.5 for your application. That's double what you'll get from regular batt insulation.
