I have been researching this same topic some--have an '05 with the 7K axles. Have already gone to 17.5" wheels/tires.

You are actually under the 14000lb axles rating since the pin weight is on the tow vehicle/front jacks. Would be nice to have th 8k rating, tho.

Cost for MR IS would be about $3200 if I use my old brakes/tires/wheels.
Problem with that is, I have the Nev-R-Lube bearings and they are past the 5-year warranty. What about your bearings/brakes, etc?

Putting disc brakes, whole shebang under the trailer would approach $6k I believe.

People who have gone from spring to IS say the difference is remarkable.
And the work has to be done at the MR plant--Dexter has some certified shops that can do the Torflex/EZFlex work
Hope this helps.
