It would at least be respectably configured for living in (bathroom, sink, heat/ac, fridge, etc). Solar on the roof would keep the batteries up with minimal need for generator run time.
If you wanted to go minimalist, you could probably get a pickup camper.
Yeah for a "fun project" I suspect he could plan ahead a little better. Not only could he have purchased a decent used MH for about $20k but you could actually get financing for a new one with all the perks. Also consider that rather than buying a truck outright, he could have just leased it for 36 months.
Missing spf records were the first thing I thought of as well. That isn't a silver bullet by any means but can certainly help your ratings while you are new and building a reputation.
If his domain is the incredibly stupid http://liminality.xyz/ then yes, he is missing SPF records. Use mxtoolbox.com to check.
What they're offering isn't out of the norm, though I might negotiate with them and ask for read-only access (non-root for servers) at least. I've been a network architect for a few years, and one of the things that comes with: loss of enable access to the routers and switches. Mind you, I was a data center network engineer for a whole bunch of years so I know my way around them. But the organizations would rather I "look, but don't touch". The great thing about it is: I can't be called for an on-call issue because there's nothing I can do to fix it.
Welcome to needing to think strategically. Take what they're offering as a compliment and run with it!
I concur. Take the small wins (especially in big orgs), and help them make the transition. You don't need rights to anything YET. That's after you learn to trust your team to bring things into the newer enterprise model and they learn to trust you. A position of this magnitude, and the experience in performing the full migration will get you even better dollars and perhaps even CIO at a firm slightly smaller, or even the same size depending on how you play it.
If you were willing to stick it out for five years and got a major offer in that time, why not stick it out another two and see where it leads?
Will it be sponsered and logo'd by nike or lockheed martin?
Constellis Holdings of course (formerly XE and Academi but most infamously known as Blackwater)
And everybody will have a "date"? No more lonely nights?
RTFA. You will need a +1 shirt worn by William the Conqueror.
Leveraging always beats prototyping.
