INSTAllING ThE BATTERIES
You will replace the standard lead-acid batteries with 
absorbed glass mat (AGM) batteries (Fig. 1) and also
add extra AGM batteries to get extended time running
on battery power.  
The  first  step  is  to  find  space  for  the  extra  
batteries and inverter. Note that whenever possible the 
inverter should be mounted in the same box with the  
batteries.
Available  space  will  vary  based  on  the  truck  
specifications, such as frame length, fuel tank length 
and empty tool boxes already on the truck.
If  additional  boxes  are  included  in  your  kit,  you  will 
need to mount them firmly to the frame of the truck. 
This  may  require  that  some  slight  adjustments  be 
made  to  fuel  tank  placement.  Be  creative,  however, 
always be cautious, as any changes you make could 
cause problems elsewhere.
If you choose to use boxes already installed on the 
truck for additional batteries make sure they are rated 
for the weight of the batteries and inverter.
Never  disregard  OEM  suggestions  relating  to  frame
welding and drilling, as they are very important.
Consider  center-mount  battery  boxes  (Fig.  2).  
Freightliner and Volvo offer center-mount boxes that 
offer four battery spaces.
If a center-mount box is not available, consider side 
frame  mounted  boxes  from  the  truck  manufacturer. 
Dometic  offers  a  range  of  prewired  battery  boxes 
designed to fit on the side frame.
