When I saw the 75311 reviews with the new Artillery Stormtrooper and Greef Karga minifigure, I loved them! The vehicle itself was ok, I understand LEGO used a 6-stud-wide design to keep the price down and cheaper for collectors that buy sets for army building. As I am a vehicle type of guy; instead of building two Trexler 906 Armored Marauders, I upgraded it to a 8-stud-wide vehicle that can seat 6 stormtroopers side by side, and 1 stormtrooper beneath a new dorsal turret. The overall Marauder is widened by 2 studs and lengthened by 2 studs (1-stud on the sponsons and 1 stud on the cockpit). The new model measures 22cm in length and 11cm in width (8cm without the sponsons). The hull is widened by using two 2x16 dark bluish grey plates on the sides of the 6x10 black plate as the base. An extra roof tile is added to the sponsons with 2x3 inverted roof tile replacing the 1x3 one to lengthen the sponsons between the lateral laser cannons and storage container. The trans-light blue engine outlets are lengthened to 4 round plates each, sitting on a 2x4 plate with two 1x2 grille pieces. For the cockpit, my first version simply widened the front and top panels to 6 studs, but the vertical frames are too wide apart and don’t represent the Marauder’s notched front well. I changed to front and top panels back to the original 4 studs, used 3x3 light bluish grey corner plates for the top panels, 28192 45 ° slopes and SNOT techniques to mount laser cannons. Each chair sits on two 1x2 1 stud plate, so they are offset by half a stud each, allowing two stormtroopers to sit next to each other side by side. The plates on the side doors are changed to 2x2 special 2-stud plates and 1x2 door rail plates. I removed all stud shooters and used original LEGO’s design for all my laser cannons, Lego included a spare reddish brown 3L bar, a black technic pin and a black lightsaber hilt for each set, so I have enough parts for all six cannons. I went through more than ten different variants of dorsal turret before settling on the current version, the thought of why didn’t I think of this before always comes to my mind. The V1.2 is 6-stud-wide with low profile after rewatching The Mandalorian S2E4. The latest laser gun mounts with elevation are designed by bruce_swift, https://www.instagram.com/bruce_swift/. Two alternate turret designs can be built at the same time.  An option to make the cockpit guns elevatable was given to me by GuCi2020 from Reddit, very smart, check it out: https://imgur.com/a/E7078c1 Better late than never 19/06/2023! I apologise for taking 2 years to rebuild my 2021 alternate build in Studio, but here it is on Rebrickable now: https://rebrickable.com/mocs/MOC-148970/Wurger Bricks/imperial-trexler-armored-marauder-alternate-build-of-2-x-75311/ I have included exploded view photos on the linked post below to show how I made the changes, I highly recommend building the LEGO 75311 first according to official instructions before using the pieces from the second set to do the modifications. Feel free to let me know your feedback and questions please! My post on the 2 different turret designs, listing the pros and cons.  Turret Comparison by R Y, on Flickr YouTube photo video:    V1.2 Low Profile Turret by R Y, on Flickr V1.2 Low Profile Turret by R Y, on Flickr V1.2 Low Profile Turret by R Y, on Flickr V1.2 Low Profile Turret by R Y, on Flickr V1.2 Low Profile Turret by R Y, on Flickr V1.2 Low Profile Turret by R Y, on Flickr V1.2 Low Profile Turret by R Y, on Flickr
