2022 SANDPIPER 388BHRD inverter

Sorry for not replying sooner, was camping in a rural area with zippo signal. Nice to unplug & get away from tech once in a while.

As far as the slides, the 2 rear slides are Schwintek slides with a power button for each slide (DS & ODS). The main cabin slides work off the same button and one side moves out and then the other. The bedroom slide has it's own control button. They are all next to each other in the convenience center above the love seat. Interesting that they didn't work, perhaps there was not enough power, or perhaps the fuses were blown for some reason. The slide motors are 12V.

The inverter would have been in the front DS compartment above the battery.
If you have the GoPower solar charge controller then you have the basic 200W panels on the roof that came standard. Your battery is probably also a GoPower 100AH AGM battery that also came standard with that package. If the fridge is indeed a 12V fridge, then you won't have an inverter. That is also interesting since as shown in the brochure I sent you, those units come standard with a residential fridge.

Thank you for your response!

I was wondering why I had 4 slide controllers for 5 slides, now it makes sense.

I think the slides in the middle and master bedroom require more power. When I pressed to slide them out they made that noise that you hear when slide is fully extended and button is still pressed.

I also found out that fridge is truly 110/propane powered and not on 12 v.

Inverter is still missing, but I think I will install all in one inverter with 48V batteries which will replace both original inverter and converter.

I am attaching the pictures I made. Converter photo is not the best one, but you can see the brand.

installing 48v will only complicate things

I would increase battery capacity......... stay with 12v


only time to look at 48v is if you intend to install a huge solar array
you can save a ton of money if you putting in 1500w or more of solar PLUS a inverter to power the whole 120v system


If you simply want to get more battery capacity to run the fridge longer off grid with a medium sized inverter + 2 or 3 solar panels stick to 12v.
 
Is there something worng with my slides or it was because I was connected to it with my truck power with no battery or external power on trailer?

I suspect slides stopped because they want the battery..

connect the shore power or generator to get battery charged
it can take several hours to fully charge the battery

after about 30 minutes the battery may have enough charge to operate the slide

I went to check my trailer again today and was able to open main cabin and rear room slides. For some reason the front bedroom slide didn’t open. It made that cracking sound that you usually hear when slide opens or closed all the way and the button is still pressed.
The only difference between what I did last time and today was today I had the 12v battery powering the slides. Last time I forgot the battery and it was power by my truck.
I wonder if the bedroom slide needs more power than what battery can supply. Can you open your bedroom slide only with 12v battery powering?
 
We had a total battery discharge.

The connection between the tow vehicle and rv only provides about 13 volts to the battery. Our slides would not work. No way.

We set the 2200 watt generator up and the slides worked.

If you had a recording voltmeter bartteey monitor you would see the slides need a ton of power.

The bigger the slide the more amperage. We have three hydraulic slides.
 
I looked under the bed and made some photos. Not sure if anything wrong with the slide mechanism.

I had similar experience when I tried to open the two main cabin slides with truck power. I could open them only when I hooked up the fully charged battery that came with rv. You are right, the battery voltage is dropping rapidly when you play with slides. I noticed that when I was playing with them yesterday.

But what confuses me is why I can’t open smaller front bedroom slide with the same rv battery that is capable of handling the bigger main slides.

Below is my RVs floor plan for reference.

good question.

On ours all three slides are hydraulic. The one with the smallest cylinder opens first. Then the second biggest. We have valves to turn any of the three off.

Are your slides all independent. Electrical? A mix?

There are a lot of folks that think their batteries are fully charged and are incorrect.

What battery bank do you have and what is the voltage of the battery before the sun comes up and the shore power has been off for an hour? I.E. no charging source for an hour.

Hi,

About the front slide. I had the same issue just recently (has only happened once). The slide would not move and sounded like most do when the get all the way in and "ratchet" It did this when pushing the button in either direction. If you look at the photo you posted showing the motor under the bed, you will see that the rod at the end of the motor has a hex on it for manual override. I just put a ratchet on it and turned it a few times to loosen it up & then the motor worked just fine. I think that it had just gotten stuck when I put it in. Regardless, I always keep the correct size socket and a ratchet or drill to operate manually if needed. Give that a try & see what happens.

This is the picture I was talking about. It's the exact same as mine.

3 out of 5 slides are independent. Bedroom slide is independent and it is the only one I am having problems with.

I am sure my battery was full because I overnight charged it at home and connected fresh to my RV.

I don’t know if my slides are hydraulic or electric, but I think the one in bedroom is electric. I can check.

Thank you! I will check and let you know.

The battery powers the brakes on the trailer. The battery will power your overhead lights, slides, water pump, and electronic ignition for your appliances when you're not connected to 'shore power'.

Since you're going to be camped mostly in campgrounds with power, you probably don't need to worry about a generator.
If you've got a propane/electric refrigerator, that's ideal for when you don't have an electricity.

Take it slow. With the battery installed, check to see what works on the rig. Then disconnect the negative cable on the battery to preserve the power. Connect it before you tow it.
Once you get access to electricity, everything should work in your rig off 'shore power.' unless there is something mechanically/electrically wrong.

I went out today to look at mine. I have the exact same rig as Rauan. My bed slide hung up again & opened fine after I used a wrench on the rod to give it a little "nudge" before activating the motor (it's a 5/8" socket).
It is a Venture Manufacturing assembly very much like the electric Lippert landing gear on a 5th wheel.

I called Venture and they said it was probably a bad stop bearing in the tube assembly & it would have to be replaced. I have the part # from them & it's $328 + shipping for just the tube assembly using the old motor.

I played with mine for a bit & it's working ok for now. If it fails again I will have to order it, but in the meantime I'll just use a wrench to give it a little kickstart. (only use the wrench when not activating the motor, then hit the button) Wanted to make that clear for safety. ;);):)
 
Thank you very much!
Your feedback is very helpful as usual. I didn’t have a chance to check it yet. My trailer is parked on the other side of the town and I will probably make it there this weekend.
Did you turn it clockwise or counterclockwise when you “nudge” it?
 
I was able to slide out the bedroom slide. It took a couple of turns before the motor could pick it up.
I noticed a couple of things that looked not right to me.
First, I saw there were some wires exposed under the slide in bedroom at the back of the trailer. Were they supposed to be hanging like that or should they be fixed somehow? I am attaching pictures below.
The second thing is when the front bedroom slide is fully pushed out it is not even. It looks like that top is not fully extended.

I guess I could try to adjust the slide out mechanism from outside as it is demonstrated on youtube videos, but I wasn’t sure if what was the cause of the problem. Is it possible that slide out adjustment was messed up when I turned the rod to start ot moving? I just gave a couple of full turns.
