    Have a 92 Coleman. Currently doesn’t have a water tank and is fitted with a hand pump faucet. My plan is to install a normal faucet (cheap builder grade ones since they are very small) and an electric water pump. I plan to have my 7 gallon water jugs outside the camper and have a hose go from the outside to the pump then to faucet. This allows me to have more space under the sink for storage and have water loaded on my truck and not the pop up.

    So my only issue is I don’t have power. Apparently the converter doesn’t work and I don’t even have a battery. I’m looking at installing a small battery underneath the sink to run my pump. It’s 12v and 3amps

    What solutions do I have without spending $150+ on a big ass deep cycle battery ?

    I would replace your converter so you have 12v. If you're looking for other ideas, any battery you use will have to be recharged...

    Something I've done before, is use a lithium drill battery. I had a spare drill and battery, so I deconstructed the drill and cut off the base where the battery insets. Then extend some wires and presto, I now had a reliable, rechargeable source of dc power. The lithium battery lasts a long time, and recharges in about a half hour.

    Another option is to use a 120v ac pump. That would solve your power issue.

    A group 24 deep cycle battery should be plenty.. and can usually be found for around $80 or$90 if you look around.

    Assuming you're camping at sites with service, just hook up to the city water connection. Otherwise, a 12 volt deer feeder battery should run a water pump for a couple of days of normal usage.

    Yea won’t be camping at many sites, mostly out in the woods. I thought about replacing my converter, but for 200 bux ,eh. The pump is basically the only thing I’ll use the battery for , I have battery led lights inside the camper that give off plenty and won’t be using other electronics .

    I’ll look into the deer feeder battery.

    I wouldn't recommend putting the battery inside the camper. Most batteries will be lead-acid and will off-gas hydrogen while they are charging.

    So I would take it out to charge. It would only be in there for the three days I’m camping. That’s why I’m looking for something small and not overkill
