I was testing or shall we say playing with mine pain in Florida goes off for 2 min with the a/c on ford service told me plug a trailer hitch stop light in the bumper plug and it tricks the truck into thinking it's pulling a trailer and won't shut off also found the 120v plug trick by accident...
I just found a cover like the Bak MX the MX sit's in the bed which doesn't work for me my equipment goes to the top of the bed I also live in SW FL try to keep it dry as possible the Leer HF 350 M open up to the front completely and sit's on top of the bed giving me just enough gap only problem...
I went with a drop in liner due to the electric connection that came with it in the bed I have a pump and a reel that will be back there and i don't have to run wire to the battery
