I believe the LDG is rated at 1000 watts as per its model number.   
There are MANY MFJ models, some for 100 watts, others 300 watts, and 
some rated at 1500 watts output, or more.  I don't know which model you 
are commenting upon.  Certainly then, there are some models of MFJ that 
are not designed to tune a 1.5kW output rig, and that is true of 
specific models of other brand tuners.  There are other MFJ and allied 
company models that are rated higher than the legal output of any ham rig.

You certainly should look inside any tuner before buying it.   That is 
why there are MFJ tuners at each ham show, with their covers off, in the 
MFJ booths, and I have seen other brands with their covers off at 
distributors that you might judge for yourself if the construction is 
going to be adequate for your planned application.

One of the great joys of ham radio is looking inside rigs and 
accessories.  The Ten Tec tuners have been made with good components, 
and adequate room to have high Q.  The use of an L network removes one 
potential lossy component from the tuner and antenna system power budget.
