I'm doing a wedding cake in October and the client requested that the filling on 2 of her tiers be caramel pecan with maybe some chocolate in it as well. I was wondering what I could use for the filling that wouldnt make the cake soggy and isnt perishable. It will need to be able to be at room temperature for atleast 3 days. Any ideas would be greatly appreciated! Thanks guys!

You could do a caramel buttercream with chopped pecans... I would say a caramel ganache (which is one of my favorite bon-bon fillings, but can be adapted for a cake), but that would need to be refrigerated, I'd think.

Chocolate Caramel-Pecan Filling

INGREDIENTS
3 tablespoons unsweetened cocoa or Nesquik
1 tablespoon butter
1 (14 ounce) can sweetened condensed milk
1 tsp vanilla

DIRECTIONS
In a medium saucepan over medium heat, combine cocoa, butter and condensed milk. Cook, stirring, until thickened. Remove from heat, add vanilla and chopped pecans or walnuts.

This filling sounds wonderful thanks for sharing
Norma20. Can't wait to try it

You're welcomed Tona, this filling is really good and not so perishable.
