Since they have made a hash of where the information in the old 2750 TRO is...
If you have the 3050 Upgrade version of the 3050 TRO, the base vehicles are in there (the royal variants are not discussed in 3050 TRO... sigh). The royal vehicles upgrades are mentioned on page 169 of the 3075 TRO denoted with a (*). Most of the changes are relatively simple and slight, usually changing an SRM launcher for some Streak SRM-2s or adding adding Artemis IV FCS to the launchers. The mechs are likely to change a standard weapon to an ER or LB-X/Ultra. The best of the royal mechs upgrade to double heatsinks (looks at Highlander HGN-732b, Battlemaster BLR-1Gb, ....). Space is made either by using a XL engine or adopting endo-steel or FF armor.
