I don't have any exp with building a ported box. So I tried the RE Audio box builder. Some people have said it's off a little bit. This is what I came up with.

My link

Edit: I made it look at, as it's going into a Extended cab Dakota. The sub will be facing up. I will be making to 2 boxes like this. But will only be putting one sub and amp for now. Then add the other down the road if needed.

And it's the IA Death Penalty 12" D2 i'll be getting.

I would try and post your available dimensions on here so someone can help you design an enclosure, I wouldnt use a box that is designed by RE Calculator.

W25xH18xD22. I will be building 2 boxes this size. One for each sub.
