I have to vote with the others - a longer cord would be best, if it's a long term install where it's at. Again, each connection is a voltage drop potential.
The RV cord is fine, but you can buy the cord and plug at a big box or an electrical supply and would probably save money. The RV cord will have to have the male end chopped off and they can add a lot to cost.
Your current cord is probably only three conductor, but you can use a four conductor when you replace it, to add a frame ground. Just for reference, both my right and my left tilt Unisaws came with cords and plugs and, as noted, were three conductor.
As I mentioned, I could get by with a 12 gauge (20 amp. That is what comes on the 3hp saws and all it calls for, but ten gauge leaves room for a bigger motor or using the cord on other equipment.
Comments from the Amazon pages:
From the manual: "A suitable circuit should not be less than AWG 12/3 wiring..." (for 3hp single phase). Such a circuit requires a 20 amp dbl. pole breaker.

220-240 volt and minimum 15 amp circuit. The plug is for a 15 amp 230 volt outlet so that's the minimum. This is for the 3HP motor.

The 3 Hp saw comes prewired with a 20 Amp 3 prong 220V plug. The saw will draw about 12.4 amps running. Use a 20 Amp 220V circuit with a minimum 12 gauge line wiring.

I run it with 240v dedicated 20 amp double pole breaker. I also use a heavy duty, 10/3, 25 foot extension cord to reach the saw.

The reason I have what you want is, I never lent it out before.
