Have a 2007 Saturn Ion.Owners manual says to pull a fuse before towing vehicle.The Roadmaster Inivisbrake system has a wire to trickle charge battery while towing.My question is if it is being 'charged' do I still need to pull fuse.I am the one who had the Saturn battery that died if not started in 3 days.Turns out that GM dealer found problem after 3 days.It was the radio 'module' not the fuse,which I had removed earlier but didn't solve problem .It is working fine now .Thanaks .

There are various reasons for pulling a fuse while towing, not necessarily just battery discharge. Especially on newer cars with more active electronic management systems. GM's Stabil-trak system, electric power steering, and anti-lock brake computers can go whacky if active while towing.
I suspect that battery discharge was the only reason on your '07 Saturn, but don't have the specific knowledge to guarantee that.
For what it's worth, a 10A charge was NOT sufficient to keep the battery on a 2007 GMC Acadia from running down under tow, even with the Ignition fuse pulled. It also produce Check Engine lights and ABS & Stabiltrak warning lights. GMC eventually decided that the entire electronic control subsystem needed to be shut down by pulling a major (50A) fuse.

If physically pulling the fuse each time is a hassle, get a switch kit, or the parts for one. This runs wires from the fuse slot to a switch you add to the dash. Label the switch tow/drive and the rest is simple.
