Leave the negs as is. There are other items that are "grounded" to the frame and get from there to the battery (7-pin, jacks, slides, etc) so you don't want to by-pass those. You can reduce your overall R by having another neg path, in parallel with the frame, battery to converter, but leave the originals there.
I had one of those Temp Assure type converters and it worked just fine. A big issue was that the Temp Assure wire has to go from the converter to the battery and finding a route for that can be difficult. It very much depends on the layout of the trailer.
Once again, a good reason to just leave the existing converter in place and mount the new one up close to the batts where it is easy to route the TempAssure wire and get a decently short run of wire charger-batt. All you need then, is to run a 120v wire close enough to plug in the new converter/charger.
I had a receptacle low down on the front wall of the living room in the 5er near the steps that go up to the front. It turned out that on the other side of that wall low down is the big cargo area up front. Ta da! I ran a 120v wire from the back of that receptacle up through the cargo bay to where the deck mount converter was put up front by the batts. Problem solved. You can find other routes too, maybe down from the bedroom or bathroom up there.
