Is the AAVE7 designation actually used? From the info I've been getting at
Amtrac.org, the LVTP7/AAVP7 series never had an official engineering vehicle, with the only subvariants being the Command and Recovery vehicles. The Mk 154 Mod 0 MICLICs I had been led to believe were mounted on standard LVTP/AAVP7s.
A good related question is when did the LVTE1s actually get retired and in terms of actual engineering work (versus just mine clearing with the MICLIC) was there anything that replaced them? I'm not familiar with a specific engineering variant of the EFV either, which makes me think the simple mounting of the Mk 154 "pallet" would be the plan in that case too.
