Bebop,
Better re-read the instructions with the table. You cannot itemize and use the table too. Sounds like your motorhome purchase with a 10 grand tax wallop is going to be the better way to go. Forget about the Table.

We're in the same boat with a new 40 ft Damon with a 400hp Cummins. I just finished intalling shelf brackets so the PSR 3000 can be set up all the time. Can't drive and play at the same time, tho.

Good luck with your taxes.
Ron
