  Hi Jack, you said you will have a lot of electronics on board. You 
didn't say what. You need to research the # of amps draw these things 
use. Many of todays "toys" are very energy efficiant, some are not. 
Will they all be on at once? We used to tow with vehicles that only 
had 37 amp altenators and they kept up because they recover fast. The 
old genorators only had 25 and 30 outputs and recovery was slow. 
Todays vehicles come with well over a hundred amp altenators.. 
BUT..they are fuel injected with many onboard engine management 
devices and reqiure large amounts of power just to run themselves. 
Your truck does use much power just to run, so you may have as 
much "unused" power left as a new vehicle. Are you going to run at 
night? headlites use a lot of power plus haveing to operate the 
trailer lites. If it were me I would just use what you have and see 
how it goes. You still have the option of changing it later. Why do 
you want to install another battery in the truck? doesn't the trailer 
have batteries on board? good Luck Arnie
