Knight and Swift are related at the holding-company level. They are still different operating authorities. Estes is an LTL network node. Shamrock is a private/food-distribution fleet, not a general spot-market substitute. Confirm equipment, lanes, and whether the company will haul for hire before you treat any of them as interchangeable.
When not to replace Swift with another carrier
If the freight still needs a Phoenix warehouse, compare Phoenix 3PLs. If you need overflow capacity rather than a dedicated fleet, compare Phoenix freight brokers. The live trucking list is on Phoenix trucking companies.
