Now that I’ve seen your reply in writing it makes sense and I should have figured it out myself .Was thinking BBS this year and thought might as well go for SS2KDoing a BBS without doing a SS1K is next to impossible, only leaving 6 hours to complete the additional 500 miles. That would require an average speed of 83.333/mph over all with no time for gas or bio breaks.
Nesting the BBS inside the SS2K is definitely doable.
