LED's are essential if you plan to dry camp, but not so much elsewise. Drycamping and boondocking require a very careful look and power supply (batteries, generator, solar panels) and power consumption (lights, A/C, etc.) and some expenditure of $$ to do it right.
If you are going to RV park camp with hook up's all the time, LED's and the rest are unnecessary. If you are going to use a generator alot and not put extra batteries etc in you camper, then you may not need them either.
Lots to consider and the lights are just part of it.
