Mate has the LM Ranger, and I've done quite a few modifications to it... but one of the most useful was also the simplest and cheapest............ a couple blocks of wood.
We found with his that legs can be a little short to level the trailer properly and then level the floor. Also if you get the trailer and the floor level the little feet on the floor may not actually make it to the ground. So a couple little bits of wood does the trick nicely
Also,
The fitting that connects the hard water outlet hose to the tank can break, and we found it hard to source a replacement try hitting up LM for a spare.
Broke it as we pulled in at camp at Quobba and dropped the whole tank of water
While I remember.
On my mates camper the advertised "100L" water tank was only actually 85L.
I'll Keep going,
Take to the trailer with the gease gun, all the suspension joints were dry on delivery. and quite a few bolts were loose (not just suspension)
Dont think I'm bagging the trailer, and afternoon giving it a once over and a lube and tighten and you've got a nice comfortable trailer to take away and you'll be happy
