Yes, should be fine.
You can have one sand bag tied so you can open it and put a cup inside it.
Then if needed throw some sand down for better traction.
Also rubber mats are helpful for traction.
No one that has spent anytime on boat ramps has not running into slippery situations.
I ran into a spot where some one had poured out a bottle of dish soap on one side of the ramp, playing a joke on his buddy.
Well I was the next guy that used it, yea real funny................., actually it was funny, but at the time.............
2WD trucks are usually OPEN differentials, this means the easiest tire to turn gets 100% of the power, so if a wheel starts to slip ALL the power goes to that slipping wheel, lol, yes not very good but that IS the way it works.
An old trick when an OPEN differential tire starts to slip is to hold out E-brake release and push down on E-brake pedal, this will slow down the slipping wheel and transfer some power to the other wheel, once you get moving let off brakes
Not easy to do this with a manual trans and foot E-brake, but with an Automatic trans and/or a Hand brake it is easy peasy
