I've got a 2 inch lift with 33"s and tow very often, mainly either a 16ft ifor or a woodchipper. No issues and I've been lifted over a year.
As said above you need a drop plate especially if your trailer has more than 1 axel to male sure all wheels are on Tarmac, I've got a Dixon bate adjustable with a 4 inch drop plate on to run level.
