New battery location install question

I am planning on installing an additional battery(s) for use as power source to run TV etc. at front of coach when parked and not running the generator for just TV. Only place for install of battery is in front with plenty of space. Wondering if I take a 12volt source from my panel (blower etc) through a switch to the installed extra battery, if it would charge that battery when coach engine running? Switch would be off when engine not running. With engine running, have 13.6 volts so would think it would be charging the battery. Anyone see a problem with this install? Running wiring from back of coach to front would be a difficult project and no room in back for addtl battery. Thanks for input.

I think it would be better to run cables from house batteries to your added batteries for charging and back up use. Not sure your fuse panel is the place to tap for charging current.

You might investigate 12 v TVs for use unplugged.

I had a 2008 Allegro Bus (40') that I installed 4 Liferline AGM batteries in just behind the front cap. We did this for the same reasons you specified, as we boondocked extensively. I also installed a 600W Samlex pure sine wave inverter to power the front AC accessories such as the front TV, the coach audio-visual setup, a Hughes Net Internet setup and the front AC outlets. I have a Word Perfect description of the setup, equipment, and charging system that I'd be glad to share with you or anyone, but I don't know how to attach a Word Perfect file to a post. Shoot me a PM with an email address and I'd be glad to send it to you. Our system worked very well for 5 years and I left it in when I traded the bus. THe WP file was developed to help the new owner understand my mod. I did this for a number of systems I modified on the Bus

If you Open the file in Word Perfect, go to "Print" under "File" menu. (don't just print using the printer icon) According to what printer you have, a choice should appear like, "Acrobat Writer; Acrobat Distiller; Adobe PDF, Adobe PDF Converter" or other PDF selection. You can choose to save with a new name or use the old name, except it will be a .pdf file extension.

I used a voltage sensing relay to automatically connect and disconnect for charging. You only need to run one hot cable from the chassis battery to the house batteries or in this case your extra battery. I am surprised that you don't already have a line run to your house batteries.

It was not set up for front batteries even though plenty of room. Was just concerned if any problems charging from front panel. Wiring is heavy enough for charging, just seemed easier to do it that way. Thanks
