You may have to move the propane tanks mounts closer to the jack... Looks like you can gain a couple of inches here doing that... You will want to put a cover on the tank to keep them out of sight...
I would also use a long shank padlock to lock down the turn screw to remove the propane tanks to keep them more secure from thief..
The batteries can be mounted on top of the two frames and extend out on both sides as long as you need it to be to support two or four batteries...
Torklift makes a great metal battery box with sliding lid for those real tight areas...
Torklift has a lock hole in their slide lid for a lock to keep from moving the slide top.
The angles can sitting on a raised section to clear the WDH hardware...
You can do the same thing for angles under the propane tanks to be able to mount tow of them...
Hopefully your spare tire is on the rear of the trailer...
Looks like it may be tight fit but doable...
