I am installing a 110vt shore power plug on the westy conversion and I am wondering where to put it on the van.

I have considered since its a syncro to install it where the fuel filler is on the 2wd because there is a round flat section of metal there 
and the plug I am using from West Marine is a round plug.

I am wondering if "shore power" in campgrounds is normally located on one side or the other with respect to drivers / pass sides

Any thoughts?

Thanks,

Doug
