Electric circuit resistance

What is the base resistance between the battery wires at the battery box (battery removed)? I measure .425.  That normal? Should be 0? Trying to see if there is a short or something else in the circuit that would drain the battery.

I'd measure current

You are looking for parasitic loads not a short. A short will blow a fuse but a parasitic load will slowly drain the battery over time. You will need to check current from the battery with “everything off".  With the amp meter hooked up, pull one fuse at a time. What options do you have? LP detector, remote fan, remote tv, amplified TV antenna, etc. are all possible. Please let us know what you find.

Our major draw was the LP detector and we were warned of this when We picked up our Scamp and we pull its fuse when in storage For even a few days. We also had a small draw  at the Converter It was replaced and all good.  I installed a battery disconnect in the battery box for winter storage and added a small solar cell just keep it topped. A little 5"X13" 5-Watt unit from Harbor freight with alligator clips.

Many thanks for the good advice. Will install batt disconnect switch and do elimination testing. Report back with the results.

solved

Battery tested ok. Turned out to be a faulty multimeter showing parasitic loads and weak battery. New multimeter battery OK and no parasitic (or very minimal) no load. Did learn a lot about loads and DC circuits from the experience for the next time. Battery disconnect is the next step. Thanks guys.
