25 should be enough, I’ve never found that to be too short. A proper size 50 amp extension will be very heavy. RV power source distance depends on where plugs are, not trailer lengths.To charge battery, maintenance charge you can use smaller ext cord gauge with adaptors, if really needed far from power, then run 12v battery power in trailer. No large loads!
I do that if parked by house if no RV 50 amp supply. Ext cord has 15a breaker for safety.
