Get a 220 Amp off a 45/5500. Denso #421000-7001; Dodge# 4801313AC. Direct bolt in from what I understand, and cheaper than aftermarket.
As far as making it home goes, sounds like you're deep cycling the camper batts, the alternator is going to full output (or close to it) and running that way long enough to get it hot hot hot while it's trying to recharge them. If you do replace the stocker with another 136A, you should be fine just driving home, I'd estimate the max amperage needed by just the truck to be about 70-75% of the stock alt.'s output.
