Water pump amp draw?

I am researching installing solar on my 1987 Scotty retro camper. It is currently put away and winterized and will be for at least another month. I converted it to LED lights last year. It has no micro wave, coffee maker, etc. so the only real draw is the water pump. So if anyone knows what the water pump draws I can try to figure out my daily battery usage to determine how much solar I need and if it is practical for boon docking with the trailer. It has a 12 gal water tank and we can go 3 days on a tank of water so I assume the water pump will pump 4 gallons a day.

I can't imagine your water pump significantly affecting your battery drain. Even if it draws as much as 10 amps, with a 12 gallon tank and a 3 gallon per minute pump your tank would be empty in 4 minutes. 4 minutes of water pump usage at 10 amps equates to about 2/3 of an amp hour out of your battery. Not even worth the bother to figure it.
