It sounds like you will need a 50 amp (220) electrical system for your computer stuff if you also want to run the AC. Depending on the location of the breaker box, power cord, and where you need the extra power it might be a PITA job.
We have a tour bus with the house systems built how we wanted it. We live in our bus about 363 days a year. Before the bus we had a short class A and it was to tight. Were set up for event camping; no water, sewer, 15 amps of power or no power, and thin camp sites.
We have no slides, large water / gray / black tanks, tinny Honda genset, large genset, large inverter / battery setup, and the list goes on.
We do anything from large company pick nicks, NASCAR, golf, soccer, motocross, and a ton of other stuff. Most of the stuff we do we are hired by a company to take pics or marketing stuff, but sometimes we go to stuff hoping to get good pics that we can sell. We design marketing stuff, calenders, and a bunch of other stuff for companies.
