Yeah, thick, low clouds make terrain hopping a real adventure! I've run into that a couple of times on flights around SEA in the F-111. Sudden pulls, sharp dives, the G stress is a real adventure! Add in tight turns around hills you don't want to climb over...whew!
I used to work on Phantoms, back in the day, when VMFAT-101 had Phantoms, and was in Yuma. Later they went to Miramar, and transitioned to F/A-18's. The ONLY good thing I liked about Yuma, was that El Centro was just under an hour away, on the freeway. Given the weather in Yuma (what weather???), I could ride my motorcycle over on weekends and watch the Blue Angels winter practice. They had Phantoms back then too, which were AWESOME to watch (and hear!)! Then they went to A-4's, which is a lousy bird for them, IMO.
Just a quick note, and I don't know if it's modeled into the plane you're flying, but the Phantom had a little quirk, that was almost always phatal to the bird, at least. The horizontal stab's hyd actuator, if it got just a little dirt in it, would program the stab full up as soon as the Weight On Wheels switch deactivated. Stick full aft, too, which made pilots happy they had the face curtain to reach for. No way they were reaching the lower handle with the stick in the way. I actually saw it one day when I was outside taking a break. He got it off the deck, and went straight up, stalled, and came straight down, all right on the base. Only ejection I ever saw personally, thank goodness.
My shop had to determine what parts of the radar could be saved. Not many, let me tell you!
Anyway, sorry for rambling. Looks like a fun plane! Good luck with the lead-sled
