@OverRunWithSons_162328 The reman engine in your fourteen year old vehicle quite possibly has more miles good use left in it than you would find in most original engines in used vehicles of the age and mileage of your SUV.
Frankly, as someone who has driven several cars long years and miles I wouldn’t worry about the reman engine. I’ve driven long miles in my several cars on a reman replacement transmission, an engine that required both head gasket and intake manifold gasket repair, and on an engine that required repair after burning out three of the four cylinders.
You bought a fourteen year old, high mileage vehicle. There is literally no way you can know how long and/or trouble free any critical components will last before needing repair be it the engine, transmission, cooling system, suspension, electronics, etc. Think of it this way, if the Pilot still had the original engine, at the high mileage on the vehicle, you would be looking at high probability of facing a very expensive major engine repair or replacement in relative near future. Instead, you have an engine that already has been overhauled to one extent or another.
From what you said on your other thread you are accustomed to owning and driving older, high mileage vehicles. So as you have undoubtedly experienced, buying any used vehicle has the advantage of lower up front cost but the disadvantage of buying unknown risks from previous use and unknown maintenance history. Your best way forward is to be consistent with proper proactive maintenance as much as possible, be realistic about the inevitable need for wear and tear repairs, and eventual total replacement at the point it makes more economic sense and/or safety to replace than keep.
