Let's say you want a bombproof dual battery setup and a high-capacity alternator, with provision for adding toys later: inverter, fridge, lights, audio etc. Also provision for adding solar input. How do you design that? Which cables/wires need to be upgraded, where do the fuses go, do you have to recreate the fusible link on a bigger scale? Is it a total PITA to buy bulk cable and do your own cable ends, or can an amateur do a good job with that? Obviously every rig is different, so premade kits aren't going to cut it for much of this. Any pointers to folks who've already done this kind of thing?
Also, component recommendations? XS Power cables (1/0?), Odyssey batteries, RedArc management(?), Blue Sea buses maybe, who else?
