This is what I went with for a mobile kit.
Personally since you're way out there I'd focus big on controlling bleeding and splinting, then on existing Med conditions/allergies (heart trouble, diabetes, allergic to bee stings, asthma etc) of whoever is important to you, then burns, then emergencies like child birth (I don't know how many pregnant ladies are usually in your vicinity, but at one point we had 3 pregnant ladies out there).

First Aid and Blowout Kit No. 2
1 - EOD bag from County Comm with one old 1980's era M-16 mag pouch attached to the webbing to separate out the band aids and triple antibiotic ointment from the life saving gear
1 - Vaseline Gauze
2 - 5x9 abd gauze
1 - Large trauma dressing
1 - OB Kit
1 - Burn sheet
5 - Sterile 4x4's
1 - Four inch roller gauze
1 - Triangular Bandage / Sling
2 - Safety pins
1 - ACE bandage with 2 clips
1 - Sterile gauze eye patch
1 - One inch roll of tape
1 - Two inch roll of tape
1 - Pair of medium gloves
2 - Pair of large gloves
1 - Pair of trauma shears
1 - Magill forceps (takes the place of tweezers and fishing debris out of the airway with these is easier than trying to do it with some short-ass tweezers).
1 - Blue bulb (Not exactly the best for suction, but it's better than nothing and for it's small size you can actually get quite a bit of spit and blood out. Actually better than those ridiculous V-Vac manual portable suction units that we used on the ambulance that's in the airway bag).
1 - Flashlight or Headlamp (IMHO a medium to low light works better in looking in the mouth than those brilliant high lumen flashlights as those wash everything out).
1- Black Sharpie Marker and a pen
1 - Combat application tourniquet
1 - Package of 35 grams Celox
1 - Adult Epi-pen
1 - 28 Fr. Nasopharyngeal Airway
1 - Packet of lubricant jelly
Meds :
5 - 81mg's of baby aspirin (possible heart attacks/chest pain)
1 - Epi-pen for allergic reactions
1 - Albuterol inhaler (not pictured, from when my wife had bronchitis...also picked up the refill.
8 - tabs of ibuprofen
4 - 325mg of regular aspirin
2 - Tabs of antidiarrheal
3 - Tabs of 25mg Benadryl
1 - Bottle of sterile saline
*Decompression Kit (Only in one kit, my '
hunting kit' where it might take several hours for First Responders to reach us just because of how far out we are - 4 out of 5 of our usual hunting party are EMT-B's, EMT-I's, Medics. Plus two nurses back at the house.
2 - Alcohol preps
1 - 10cc flush syringe of saline
1 - 14ga 3 and 1/4 inch
Boo-Boo Gear :
10 - Band-aids
1 - Tube of triple antibiotic
For Diabetics :
1 - Glucometer sticks (one member of our usual hunting crew is a diabetic)
1 - Tube of oral glucose (diabetics can tolerate high blood sugar for quite awhile, a low blood sugar is a different story).
The sky's pretty much the limit on how far you want to go with this, but that's what I've got going.
