st: Checking Tobit Normality Assumption

Has anyone developed a procedure in STATA to check the normality assumption when using the Tobit model? I am aware of a rather elaborate procedure in LIMDEP, but I don't have that package.

I have survey data on the annual salary that respondents would require to make a certain career choice. The data is both top and bottom censored. I know I could also analyze this data using oprobit, but I'd like to keep the more natural interpretation allowed by the Tobit coefficients for my application.

Much thanks for any suggestions.
