Rough Amazon prices:

4/0- 20' 86.00 (including 5 4/0 3/8" copper lugs)
Since my last cables lasted 12-13 years...my reasoning is, YES, over-kill, no doubt, but cost over the life time of the cables, a bargain! If I was re-running cable to my inverter(2500 watt), I certainly would have used 4/0 cable too...but for a 1996 MH, the old cables have held up well(knock on wood).
To the OP...I guess it's up to you and what makes you happy, whatever you decide, I'm sure it will be Great! :-)
