Trying your megamod on my second install (slightly adjusted though) i discovered really nice mods i never tried before!
At first launch, biggest immersion improvment is definitely the MadMaxs_SH5_Subdiesel (mono) v2
Quite incredible sound on my rig! I love it
Your Equipment_Upgrades_Fix_v1_4_Patch_1 (available by date) V8 by sober is VERY welcome too
Other nice touch is the water droplet sound instead of the traditional "clic"!
I'll have to use the keymapper mod though, because i really don"t like the stock keys for mouving...gonna be an easy change.
