popuptoaster, the Megalith looks exactly like the Ofna Titan Twin......

And as has been said Hong Nor is the manufacture and in the USA they are rebadged as Ofna and in the UK as Ho Boa and in Europe as Jamara.
The Titan Twin was a limited production of 500 hence the lack of response, but Ofna (Hong Nor) are producing them again as there is demand for them.
There is also the Titan which is a single engined truck and I think exactly the same except for the 2 engines on the Twin and a few extra's.
There is a web site just for the Titan trucks..............

The Titan twin is available from a Hong Kong dealer, when they get the stock from Hong Nor!!

And it is just $500 (£290) plus $102 shipping a total of $602 or £346 a lot less than the UK or US prices!!
