It is unfortunate that specialty alternator manufacturers like Lestek no longer supply the RV market. The ND high amperage hairpin alternators do not have the rectifier nor heat sink capacity to handle loads above 150 amperes for any length of time. If you are curious you can look up a Leece Neville 4900 JA series alternator on eBay. The 270 ampere unit has 12 rectifiers = 6 @ 50 amps rating. This unit can withstand constant 270 amps output. But! It's a monster size wise so large that it is an absurd idea. It uses a pair of B belts and had a long duration RPM limit of 8,000.
A better idea may be to use a large case fixed mount alternator and let a belt tensioner do the adjustment tightness.
And none of this addresses the necessity of integration of the unit to the vehicle computer. What a sad state of affairs. :(
