Just be sure to run your fans on relays.... I've seen many people try to run them without and that's serious no no!
I just added a SPAL PWM fan controller to my Nomad... has the first fan come on only half speed and slowly speeds up that fan IF needed - once Fan #1 goes full steam - fan #2 comes on... it also has them BOTH come on when your A/C is on... and has a 'cool down' cycle for 30 seconds after you turn it off... Nice system for nominal additional cost IMHO. Really keeps the noisy fan issue at bay most of the time.
