if you can go 100 miles or so between gas, pitting is pretty straightforward with one chase vehicle. I.e. they can typically catch you every 2-3 pit locations. if you have less range, you may need to go to the remote pit at rawhide and will need two chase vehicles in that case or hire someone like Baja Pits. this year, BP is offering a one pit option for rawhide, I think. of course, we won't know for sure until they release the pitlist/book. if you have time, you should come out this year and check it out, maybe help one of the chase teams to get an idea of what it's like. we (solo riders) are pretty friendly with each other and help out where we can.
When I did it in 2016 I used 2 chase trucks and BFG pits for Rawhide. Worked out well for me. If you can’t afford 2 trucks then just use one and hire a pit service. Typically Baja pits is congested in the beginning of the race so if you are competitive, avoid using the first few pits if possible and use your chase team instead.
