ok...i loaded up TMO and it ran fine. i am shocked because i remember a problem that i had to mod around. here is my config.
Generic Mod Enabler - v2.6.0.157
[C:\Ubisoft\TMO_2_5\MODS]
100_TriggerMaru_Overhaul_2-5
110_New Narwhal K v 1.8.5
130_New Narwhal TMO2.5_Support
the only feature that did not perform properly was External View. that problem was solved by assigning keys for external view (doh).
and...it works with wTw.
Generic Mod Enabler - v2.6.0.157
[C:\Ubisoft\TMO_2_5\MODS]
TMOwTw 2.50
110_New Narwhal K v 1.8.5
130_New Narwhal TMO2.5_Support
i do not have the other two mods you are using so i would suggest that you try the config i used above and then add each of the additional mods, one at a time, testing at each interval. your problem could be related to one of them.
p.s. i may be remembering my difficulty driving the Narwhal with RFB/RSRD which i played recently.
