Earliest platform saddle (lvl 50), then place storage boxes, then mine all the metal until too heavy, then go back, then smelt ALL THAT IRON (I had 2, sadly, can only request my 2nd, because 1st had platform saddle), so that is the downside of platform saddle; cannot request.
On Scorched Earth the Paracer with its platform saddle is a needed tame. You can put a cannon on it and use it for taming Rock Elementals or use its high weight and health for carrying large loads of supplies around through dangerous areas.
Put a tek force field on this thing and bam. You have a mobile impenetrable shield that you can walk right into a base and to tank turrets slowly while your enemies watch and can do nothing but try to rocket it down.
You can put an outstretched platform with railings on front of paracer and then put moschops on the platform then jump on Rex or giga and kill stuff but don't harvest so when the paracer comes the moschops will eat the corpse and gather tons of prime.
