Should I get a rotomolded cooler, and which brand is best for a jobsite?

Yes, get a rotomolded cooler. Pelican is the value king—same shell and ice retention as Yeti but $50–$100 cheaper. Orca has the best drain plug. Yeti is fine but you’re paying for the logo. Get a Pelican 45 or Orca 40; they’ll survive a jobsite and outlast your truck.
