securing propane tank

[ltrcrr]

Is there anything on the market that I can use to lock my propane tank and battery securely to my popup? I will be parking over nite and leaving it unattended and don't want to come out in the morning and find things missing.
I plan to keep the propane on over night to keep my fridge cool...
 Thanks

I don't know how your tank is attached, but mine had a long bolt that went thru the frame of the camper and thru holes in the bottom of the propane  tank itself.  

When I got my PUP - one of those bolts was missing, and the other was rusted solid, I had to cut it to get the old-style tank off.  Rather than using a bolt to attach the new tanks - I used these hitches -

the way my tanks attach, if yours attach the same way, I'd think you could simply put a padlock thru the frame and bottom of the tank on one side to keep it from being lifted out of place.

As for the battery, it depends on how it's mounted on the frame, too.  I don't have a battery, but I used to work at the store in the link above - and I know they sold battery cases that could be bolted down and locked shut.  they bolted with "U" bolts to the frame that the nuts fastened INSIDE the box, and once the battery was installed and the lid closed, the lid could be locked with a padlock.

I also think that there are covers for the tanks on the front, that once installed, might be able to be locked - but I've never looked into them.

A simple padlock through one of the mounting holes on the propane tank would work fine, without getting too costly. The hard covers for tanks do have a padlock hole on them, but I've never seen a single tank hard cover. A battery box is the best answer to secure the battery. Clamped on to the frame and a padlock should work.

I use a bike lock to lock my propane tanks onto the popup. I run the lock through the handles and down under the angle iron frame the tanks sit on. I have the heavier chain type bike locks for this purpose. When buying them I looked at the combination for each and picked out an easy to remember one for each.
