Need to rent a tow vehicle.

Ideas for renting a truck for some long distance (5 to 8 hour drives from home) towing of my trailer?

Hertz Equipment Rentals has like a 100 mile range and said they would let me go to my local camp since there's a Hertz less than 100 from that location, but not so much for towing to Yosemite or Sequoia.

My current ride has too many worry points to use it for those trips.

Enterprise doesn't have trucks with towing packages and they say no to towing.

Not ready to buy a new truck, but don't want to avoid long tows because of breakdown worry.
