If y'all go to the Goodyear site there's ratings on those marathons--- I've had the same problems but I also tow at 75 Mph - until last week... I stay below 65 now and keep them @ 50 psi.
I lost 3 marathons last year and one last weekend...
tirerack.com has the Kumho 205/ 70 / 14s rated very well-- they are load range D whereas the Goodyears are C... there is alot of talk about this on the mastercraft forum as well. google the problem...
it's been over 100 here fore a couple weeks and that doesn't help but it is obvious there's some issue/ defect in those marathons .
