Battery or not?

Sorry if this is repetitive, but I'm confused. Have a 2006 Rockwood Freedom 1640ltd. I've been give a range of answers.

Can I run anything on this pup with a battery? The seller told me the pup doesn't have, and never did have a battery, and that nothing runs on battery.

Another Forum member told me "of course it has a battery. That's the whole point of pups, going off grid.

Somebody else went down the middle and said the you can use a battery, but for what it provides, it's not worth it.

I don't know. I don't see a battery anywhere. If I should get one, I know a deep cycle is the way to go, but what size? Where to put it? How much power will it provide? Any information referrals I can search?

Thanks

OK. Do you have a water pump? What does the label say?
Do you have an absorption fridge? The control board operates on 12V ( might use propane for cooling).
Do you have a suburban furnace? The control board and fan run on 12V. That can be provided by the converter or a battery, but it has to have 12V.
Look at the lights. What is the voltage on the bulbs? They are most likely 12V. Again they can be powered by the converter or a battery. I have never seen a newer (> 1995) unit that does not run the basics on 12V. If that is the case, you can add a battery and run the basic items.

The seller lied to you.
The fridge, lights, furnace fan and water pump all run on 12v battery power.
The fridge can also run on propane or 120v AC shore power.
The pup has a converter, which charges the battery when plugged into shore power or a generator.

Popups are designed for being able to run on just 12v battery power.

I know because I've owned two popups.

Looking at the floorplan, both the fridge and furnace were options.
And it may have a hand pump water faucet, therefore no electric water pump.
So if yours has none of these, the lights still need 12v battery power.
The previous owner may have always kept it plugged into shore power and never installed a battery.

We owned an 04 Starcraft pup that had no provisions for a battery. Fridge was 120ac/or 12vdc no propane option. Hand operated water pump. All the 12v stuff ran off the converter. The only battery was a gel cell for the break away braking system.

If the fridge could run on 12vdc, how could it do that, if there was no battery?

My 1988 Coleman pup had no battery. Fridge ran on 12VDC from the converter if you had 120VAC available, OR it ran on propane, OR it could run on 12VDC from the tow vehicle going down the road. All my 12VDC stuff ran off the converter. If I had no 120VAC, I had no 12VDC.

X2. Now that I think about mine had the propane option but I could never get the pilot lit. It also had its own 120ac cord which plugged into an outlet behind the outside access panel. But back to the original issue the pup did not have any provision for a battery except for the runaway brake.

Based on my analysis of the 2006 Rockwood Pop-up brochure, the battery box and associated wiring were an option on the 1640LTD. It came with a 12A converter instead of the 25A in the larger/more expensive models.

Assuming the seller was correct, putting in a battery and the wiring is doable, but not a 2hr job. Since the battery option was apparently never ordered, I have to ask what other options you have installed. Factory options that would make use of a battery are:
  • 1.9 cu ft 3 way fridge (factory option, ice box was standard)
  • heater (again, a factory option)
  • electric brakes (again, a factory option)
  • water tank, electric pump, sink (I don't know if these were standard or optional. You could have a hand pump, sink, and tank. My first PUP had that arrangement.)
  • the heated mattress pad option requires 120V AC, and will not run off the battery.
If you don't have any of those of those options installed, the ONLY thing a battery is going to do is run the interior lights while unplugged.


Starting at the front, my guess is that you do not have the big 7 pin electrical connection to the tow vehicle that most all RVs with batteries use. So you would want to convert to the 7 pin connection on both camper and tow vehicle to give battery charging while towing.



The 7 pin connector also provides for electric trailer brakes. If you don't have installed electric trailer brakes, as you weight down the trailer, you will want them - especially if you are towing with a 6 cylinder vehicle (mid or small SUV, minivan, small truck).


The battery box goes on the tongue, either in front of or behind the propane tank(s). Normally, 2 rails are tacked on across the tongue a-frame, and the battery box(es) mounted to that. It does add to the tongue weight of your camper.



There is going to be a fair amount of wiring to do - you can do it yourself if you are comfortable with that kind of thing.



The heater fan is the big draw of power, especially if you convert your lights to LEDs. If you don't have or run the heater, a size 24 deep cycle can last you a week. If you run the heater for 4 hours/night, the battery will only last 2 nights. On our A-frame, we installed 2 6V golf cart batteries to carry the heater for 4+ nights without recharging.


If you are going to be dry camping or boon-docking on a regular basis, and using the battery, you are probably going to want to upgrade your converter (or use an external charger when power is available).


Let us know the specifics of your PUP - what electric-using options or mods it has or doesn't have.


Hope this helps

Well, I owned two popups, a '72 Starcraft and a '93 Viking, both with basic equipment.
No water pump, no a/c, no electric brakes and no stereo but both had batteries.
Never knew that you could get one with no 12v battery setup.

I guess I assumed that it was kinda mandatory, since it has 12v powered items.

Maybe since I lived in California, where virtually none of the state parks have any electric hookups, dealers didn't carry these types of popups.
