I just want to lead off as many have done before me.... this is one great site.:ro)

Recently I had my original altenator die, the parts store tested it and it was putting out no volts but everything else checked out ok. My question is, the altenator I pulled was a 100 amp and that matched the code on my glove box, but the parts store sold me(aka recommended) 105 amp re-built altenator will this cause any issues down the road or should I take it back and get the 100amp altenator??? I do haul a 5000lb fifth wheel in the summer so maybe going to the higher amp altenator would be a good idea.

I don't think it will hurt anything, just put out more power.

Your origanal alternator was a cs-130D the replacement is the same style and should not cause any problems. Personally I would go back and get the cs-144(124&140 amp alternators). It is a pretty simple conversion, on yours you have to change the regulator plug, remove the rear mounting bracket and install a 5/16" charge lug. The cs-144 is a much heavier duty unit(physically larger) and puts out around 80-90 amps at idle versus the 60 the cs-130D is supposed to put out.
