This Pete, spotted this morning on the waterfront, could pretty much tow anything too. It is operated by Lussier, the used truck and equipment sales outfit from Ste-Julie, QC. It arrived towing a truck for export. I didn't see what it was towing, but it could have been anything from a school bus on up.
I've posted about them before - there's more info at http://www.lussier.ca/
The towing gear is mounted to the fifth wheel and can be removed if the truck is needed for towing a semi-trailer.
