As a trougher, I wish being an ART would have been available to me at the time. The condition of being a trougher (bum is what the Guard calls it) is more nuanced than meets the eye. It really depends how your unit doles out the cheese, and how many mouths are trying to feed from the pot at the same time. That leads to surprisingly different outcomes for bums across the system.
Fighter vs heavy. FTU vs combat code. Non-alert vs alert. RPA majority allocation versus MPA majority allocation. It's all over the map. So you're gonna get dramatically slanted answers on here.
In other words: Being put on 30+ orders, all the way to 360 day continuous MPA/RPA is a lot different than the lost decade years of being told local-only, non-commuter sub-30 day chunks. Which in my case were I kid you not, 4 long tread-water years of 4-day orders. Worked like a whipped mule for 60% of AD for more time at work. My AROWS-R account looks like the g-d Library of Congress with that many orders. That's a BIG difference when you're getting paid no per diem, and you're taking R/C-BAH (aka Type II) in lieu of BAH type I. That's where the 60 cents on the dollar paycut comes from. Being an ART is actually a pay raise from that, and bear in mind, we all understand the dramatic paycut doing this job as an ART is for the same hours worked, versus AGR or straight up regAF status.
Btw, this idea that a bum only is expected to fly may assume facts not in evidence. For all we know, if your unit is paying ya in RPA vs MPA, they can just as well ask ya to do qweep for them if you want to get paid. At that point you might as well take the ART job, even with the healthcare TRICARE ineligibility hit. So again, the devil is in the details here.
Otherwise, neither option is going to create problems for your ability to accept a training date at an airline (you might **** off the unit by chucking back 90 days of MPA on them on 4th Qtr just because Delta gave ya an August class date and it's July already though), the way the AGR status potentially does for instance.
You don't want to be like one of my ex-squadron buds who got told no to his AGR curtailment with a Delta CJO in hand. Yikes.
The world is replete with opportunity costs. The "problem" with my advice of taking the ART is that I'm coming at it from a head of household POV. You have a sugar mama, so these nuances seem immaterial to you. All you hear is "the full timer has to do qweep; the bum only has to fly and flock off the rest of the month". I'm with tankerdriver on this one, being an ART doesn't mean you can't fly your rear off. I've known ARTs that end up no kidding troughing themselves. Getting on ridiculous LWOP stints and doing MPA/RPA like bums themselves! It would be absolute blasphemy to allow something like that to occur in the presence of hungry TRs wanting to trough; but in their absence? Absolutely happens. Hate the game not the playa type of thing. Again, nuances.
First world problems. The pot can dry from under you, but in theory the trougher (assuming not taking a de facto AGR chunk of mandays) has much better scheduling flexibility and days off shuffling ability for said paycut. Better healthcare as well under TRS imo depending on region (I find FEHB too expensive). So your call bud. With a sugar mama providing most of the lift it's kind of humblebrag for you to come ask these questions to be honest, but hey more power to ya.
