We have a 2wd 99 F250 7.3 diesel Crew Cab short bed which is right at 7,800 without our camping stuff - water, food and other supplies.
For awhile I felt like we could get stuck on the asphalt next to the sand - kidding - but close.
We got some Treds which really helped getting unstuck! Then at 230,000 miles I got the diff rebuilt changed gearing from 3:73 to 4:10s and replaced the warn out posi with a Detroit Locker. What a Difference!!!!!!!
We still can get stuck in sand if I am not forceful on the throttle - but not like before. We have powered through some long stretches of sand and loss rock with no issues. I have to add that our SD has a 6" lift on it which helps a lot on mountain trails with holes and bigger rocks.
I would suggest always going with another rig and tow straps, winch and test your rigs capabilities now and then as in try something that looks like you will not make it (with in reason). Also what you are doing is learning how to get your rig to do what it needs to do to get through a spot (driver training).
Truck is/was stuck, it is sitting on treds waiting to see if we can back out with the trailer. Jacked it up filled the holes and let the rears down on the treds.
