i pull a boat across the desert, 500 miles round trip.100-115 deg. I watch tranny temps 204-215. All seems ok, but I just feel under gunned compared to my old duramax.
Am I just asking for issues towing 6500lbs?

No you should be fine. But of course your gonna feel under gunned because your old truck was a diesel and more well suited for towing
cant compare diesel and gas engines when it comes to towing.

I figure the weak link is the tranny, but doesn't seem to get hot. I was Leary of buying the raptor, I could have done a f350 for the same price, but it's not a raptor.
FYI, 480 lbs of tongue weight, levels out a stock 2014 screw.

I agree on the transmission being the weak link. Even though the temps you see are not that bad having a transmission cooler might not be the worst idea, maybe look into one of these Transmission Cooler Kit - RPG OffroadRPG Offroad

Should be fine. I have towed that more than once with my truck. No issues, held up well and strong.

You have plenty of motor and you're below the towing allowance. Assuming your setup is good, I don't see anything to worry about.

Your temps seem normal. Towing my 7000lbs toybox I saw temps as high as 210° and in the dunes I've seen the temp go as high as 215° so you should be OK.
From @HAYNES OFFROAD
Ive spiked my trans temp to 235° in the dunes running really hard on a 80° day with factory ATF. Once i converted the trans to Amsoil i havnt seen temps go over 220° in the same conditions/driving.
190-205° would be considered normal operating temp for our trucks.
205-225° would be expected during spirited runs.
225-250° would be extreme situations such as hill climbs, or hard desert running. Let cool as soon as possible.
275° is the absolute max, VERY temporary operating temp (such as a long hill climb), before you will considerably reduce the life of your ATF and trans. Let cool immediatly.
At 300° you WILL damage internal transmission parts, including warpage of metal parts, degradation of clutches, and melting of seals. Transmission oil oxidizes, (forming varnish-like substances causing further clutch slippage and compounding heat build up) and transmission oil life is extremely short. If you see this temp, break out the check book.
Every 20° above 200°, oil oxidation rate doubles.
For EXAMPLE, say, at 200°, ATF life is 100,000 miles,
220° ATF life is 50,000 miles,
240°- 25,000,
260°- 12,500,
280°- 6,250,
300°- 3,125 miles.... And so on...
Obviously those numbers arnt going to be exact and is only hypothetical, because every transmission sees differant temps on a day to day basis, as in one day, your trans will only see 195°, while on another it sees 220°....
Obviously a larger cooler with fan, would be one of the better ways to control trans temps a lot better. Couple that with some Amsoil ATF and finned/deeper pan and that would go a long way.

Agree on this, anybody know if this is a plug and play unit? I have had trans coolers in the past, I don't like cutting lines and hose clamping something in line
