It is best to carry a spare fuel filter with you at all times, even if you can not change it, you can get it down at any 5 minute lube place (if they have one on the shelf or if you bring your own). If you get hit with bad tank of fuel, you can plug the filter in 100 miles, and will lose a lot of power.
But with modern fuel systems, and changing to fiberglass tanks back in 2007, it is much less likely that you will get a bad tank of fuel. Back in the 60's and 70's, it was possible for a bacteria bloom to grow inside the old steel storage tanks underground where it is fairly cold, thus the recommendation to buy fuel in a place that refills it's tanks every week or better - every day they get a new tanker of fuel delivered!
Did you buy a 2500 pickup or 3500 truck? It looks like you have a substantial trailer, and would need the 3500 truck to avoid overloading the tires found on the lighter duty 2500 pickups.
Have fun camping!
