You can run both a towed and truck mounted version of the same 105mm gun in the Reserves. The towed is where you learn your trade and then expand on the mobility side with the truck mounted ones. The Brigade HQ is going to hate dedicated gun trucks as the other units can't borrow the truck. The 105 and 155 can use the same FCS as well. The 105 still outranges the 120mm mortar and the tractor can carry more stowed rounds than a 155. Mobility and ROF is nice, but if you go back and reload every 20 or so rounds, that's going to impact your tube availability. 20 rds of 155 is a bit over 2,000lbs. With a mounted gun you need a 10 ton truck to carry crew, equipment, gun and ammo. A mounted M777 is likley in and around 4 tons by itself. whereas a 105mm mounted gun can get away with a 5 ton or as small as a Humvee except you need two trucks. The EVO-105 system from Korea appears to have about 27-30 stowed rounds and room on the deck for more. The Archer has 21 stowed rounds.
