Looking at 3 different converter manufacturers surge current limit resistance:
Parallax: 2 ohm
Progressive Dynamics: 1 ohm
Iota: No thermistor, ac source resistance and converter input resistance is adequate.
None of these are failing! Their surge current limit is perfect in protecting all parts.
Tell me again why do you want 5 ohm?

without schematics it's hard to determine how input current is limited in each design.
The PD and Iota are not power factor corrected, the boondocker is. The PD and Iota have lower max output current.
And, there are multiple ways to limit inrush current in a design, an NTC thermistor is just one very common method, but not the only way by any means.
Kinda like saying since my mercedes needs only a small battery, no reason to use two big ones in my duramax, just put one small one in and it should work fine.
