Part needs max temp increased
Heatshield needs some hand-tuning of the usage curves/etc

Balanced for 1600 peak temp, ~450 ablator used, for a mun to 30k capture. Could possibly be tweaked a bit more, but need to gather more information regarding re-entry from duna/etc returns.

Update

The heatshield is fine with me now in RSS+RealHeat, with this patch[1] installed. It has 187 ablator left when performing a LEO lifting reentry. Might not be enough when reentrying directly from the Moon or Mars.

[1]Patch is:

@PART[*]:HAS[ModuleAblator|ModuleHeatShield]:HAS[!%RSSROConfig[*]]:AFTER[DeadlyReentry]:NEEDS[RealSolarSystem,!RealismOverhaul]{
    @MODULE[ModuleAblator|ModuleHeatShield]
    {
        @name = ModuleHeatShield
        // Globally, the base is 5. Consider making this 8.75 for all but Mk1pod
        @lossConst *= 0.0008
        @pyrolysisLossFactor *= 50
        @reentryConductivity = 0.01
        @ablationTempThresh = 1000
    }
}

That patch does literally nothing for the heatshield on that pod, at least not for the SSTUHeatShield -- that patch would only effect DRE/stock heatshields, neither of which I support.
