[Mobile-Portable] Solid State Amps - Battery & Floating Charge?

[kd4e]

I am combining a pair of solid state amps.
They each use a set of four 2SC2879's.

They each may draw 75amps if driven to full power.

I'd like to power them from a large deep-cycle
battery or two.

I'd like to be able to use that/those batteries
base or in a large travel trailer.

What large capacity deep-cycle battery(s) do you
recommend for this application?

When *base* is floating an Astron VS-50M 50A power
supply across the battery(s) sufficient to hold them
up during surges?

When operating fixed-portable from a *travel trailer*
should I anticipate the need for a small generator
on the towing tongue rather than tapping into the
travel trailer's power system?

If I use the dual-unit amp *mobile* in my 1996 Chevy
1500 van should I use:

1. An auxiliary battery?

2. A beefed-up battery in the van?

3. One or more of the large 1F or 2F caps the sound
    nuts use mobile inline with the amp supply as a
    power surge buffer?

4. Do I need to beef-up my alternator?

5. Other?
