Much better spring and fall and not so crowded. If you are coming from Western WA it will seem really hot and there are few hook ups to run the AC.
Actually, if I'm reading your post correctly and you're saying spring and fall are less crowded, that is not true. Spring and fall are the most crowded times in Moab as that is when the nicest weather exists.
Arches Devils Garden campground is closed through November 30th, 2017. But, there are many private RV Parks close by in and around Moab which do offer FHU so one can run air conditioning if you have an AC unit in your RV.
I've been to Moab multiple times during the spring for ATVing but am headed back this July with the family and TT. Yes it will be hot during the day and as already mentioned, you need to be on trail early and everyone should be bringing lots of water. Sunscreen, wide brimmed hats, long sleeved, loose light colored venting clothing will all help deal with the heat. Be prepared to stink :)
