Build-my-own 30-amp extension cord
My trailer came with an approximately 25-foot long power cord, which depending on where I am, maybe a bit short. I've been looking at extension cords and they all seem to be a bit overpriced for what ...

Funny discussion, 'cause here in Ontario a 100' run from the camper to the power post wouldn't be unusual at all, sometimes longer. I've run as much as 140' using 10 gauge, no issues at all - it's all about unloaded source voltage, how much current you're pulling. and therefore how much voltage drop you can expect. Nominal source voltage here in N America is spec'd to be 120 vac but if you run into a situation where for whatever reason it's say 110 vac then obviously you want to limit your total current draw so voltage drop isn't excessive. My Progressive EMS was set to trip @ 104 vac so I always make sure incoming source voltage under load meets these requirements so the EMS won't inadvertently trip. Plug your numbers into this Voltage Drop Calculator and you can predict exactly what the end result will be.
