I also have the RFM M1A1/A2 w/ full int and ordered a seperate int because no matter how I try to figure a way to build it, so much of it will still be hidden. I'm just going to build the seperate int as a stand alone that I'm back and forth on mounting to the same base or as a seperate base… and I have the RFM M4A3 76 VVSS(W) w/ full int in the stash. I keep hearing that I made a sound selection with that one…
As for the Border Merkava Mk2D, Rob Adams of TheModelingInsanityPodcast has been building it off and on in our Discord Build Room. I've been following that build very closely as I was suppose to build mine at the same time. Other commitments kept me from starting which turned out to be a blessing in disguise! While it's been a beautiful build that has gone relatively well(you have to know Rob to understand relatively well with him as he likes to really push the boundaries on trying to open up these tanks to show off the interiors), the tracks have been a full blown nightmare! I'm not even sure how many hrs he spent prepping them, but I do know it was 6-8 hrs of assembly for 1 SIDE only to have it fall apart!!! The kit is now sitting off to the side, awaiting aftermarket tracks! Once I see which ones, how they go together AND hold up as he installs them, I will order mine Momma didn't raise a complete fool, lol
