$180/day hauling HAZMAT, good or bad?

Over the past, few months, I was looking at transferring within my company over to the Phoenix area for weather-related reasons(after three winters, I'm mentally scarred by it).
I looked at a few apartments in the area and got a general idea of what was in store should I make the move.
I then visited the terminal down there and got some further detail on the copper-concentrate/HAZMAT hauling operation they had openings for.
While the job seemed pretty straightforward, no OTR and all local/home at the end of shift, the paycut was somewhat of a disappointment for me.

Hauling milk where I'm at right now, my nightly is between $200 and $300 depending on the amount and dairy co-ops I'm pumping.
Despite the winters we've had here, the potential to keep making this amount and saving some of it for other things I'm planning on doing seems too good to just make the move back to a familiar climate.
So apart from experiencing more of a night-life, hot weather, and a true desert environment I'm used to, does anyone else here think this rate of $160-$180/day for placarded HAZMAT is too low to make such a move for?

I've already got my doubts, but added opinion would be nice in further gauging the decision making.

 

Will you be working same amount of hours?
Driving as many miles?
Working as many days?
What's the difference in cost of living?

Same amount of days and hours as the assignment I've been on for the past, going on three years.

Right now, I typically do a few in-town dairies and a few located about 40-60 miles away in Friona and Muleshow.
Longest miles I've done so far were night-runs out and back to either Dalhart TX, or Willard NM from Clovis.
Only over-nighters we've done were Norman OK and back, and we were usually paid pretty well for that and a motel room for each trip.

This Phoenix position usually entails about 400 total miles of driving a night with some time spent getting loaded or unloaded at the mines.
Cost-of-living varies through Phoenix metro, but the nice areas are typically running at about $560/mo for 2/1 apartment and utilities extra of course.

On top of the pickup truck payment I'm still making, I'm feeling I should probably keep plowing it through with the dairy assignment they have me on until I get it paid off.
I figure one less, big bill to deal with and a paycut like that would be a little more forgiving.
So for now, I've called off the transfer and even got bumped to a "set-days" schedule that opened up on top of things.
It may be purely coincidental, but it seems like the pot got a tad sweetened over here.

Apart from Phoenix, I'm also looking at a possible company transfer to the Portland area for their larger availability of helicopter flight training opportunities(why there are so many helicopter flight schools in a cloudy, wet area is beyond me).

All-in-all, I've been with my current company longer than any other trucking, or even non-trucking job I've had.
And most of their gigs across the country are all local/dedicated/home-every-night and day jobs.

 

Yep. While some have mixed feelings about it, they've treated me alright for the past, few years.
Haven't really found anything better than this yet, or haven't really been that coerced into looking.

Outside of non-truck things I've become interested in like Insurance claims/investigating and helicopter piloting and maintenance, I feel I've finally found the "keeper" being I've stayed at one place this long.
