Agree with this and lithiums have a lot of benefits but it sounds like the op has a tight budget.

for an inexpensive option lots of people love these.

You need at least 2 and need to wire them in series to get 12 volt. They are also heavy and you have to top off the water regularly. Trojan used to sell an autotopoff product but that would add to your cost. Low tech and more maintenance but they definitely work. You could always start with them and upgrade to another type down the road.

You might find good deals on used batteries from someone who is upgrading to lithiums.

yeah I do have a tight budget. I am going to be saving up money over next few months to buy the stuff I need. I have to get a new water pump,wire,the distribution center,batteries,stove top that runs with propane,a fridge that's propane and a water heater.
I just realized that what I thought was the water heater isn't a water heater at least it don't look like it, I am not sure what it is I am attaching pics of it.
it does have duct work coming from it but its not the furnace as that's further down the hall.

Looks like a furnace to me. A hot water heater should have a drain plug to empty the water from the tank. Whatever that is its in rough shape

To save some money you can use some residential appliances in an rv. We have a residential gas range and fridge in ours. You will prob need to use an rv heater and hot water heater and fridge if you want propane.

I have seen some people use heaters like this but not very often

There is probably more you have to worry about that to use those safely in an rv and that one may not be safe for indoor use. Not recommending it.

That's a water heater. Not sure of the brand but it has a pilot flame you have to light manually.

That's a water heater.. Not sure of the brand

American Appliance hot water heater. Look at label to right of controls for model, build date, capacity etc.

How do you drain the tank on that one? I dont see a drain plug.

 

[ferfer]

I dont see a drain plug.

Not sure but can you see the heater back by looking under trailer? Wild guess is the plumbing and drain there.
