Its all about your budget .
Heres mine . 2015 Holden Colorado, open trailer , tent . We sometimes dont get power in the pits so I carry a small genny . Spares are hoses , set of plugs ,fuel pump/filters, waterpump , alternator , fanbelts a little oil , front wheel bearings , carb bits, dissy cap/ rotor/leads/msd box & coil , intake/exhaust manifold gaskets , . I often carry a spare set of axles with bearings plus seals and currently a spare pair of radial slicks on wheels .
Running a BB mopar you are not going to find any parts at or near a track . There is only 1 other guy i know regularly racing a bbm in competition and im the only B body .
How did Kermit put it ? "Its tough being green "
But wouldnt change a thing !

PS buying a 12v esky/fridge was one of the best things i did .
