Agree.
PQB: Unless dramatically more 12V items were installed and these items will be ON during the same time, there's need to install a larger than factory size Converter. Its like the vehicle sizing engine thing. re: Vehicle came with V6, doesn't endure high loading or towing, then why upgrade to larger V8 engine? Much larger size engine would be a waste. Same with RV Convertors. If it came factory with 45A, then why upgrade to much larger 55A or 60A model?
If wondering, my previous RV's factory convertor blew. It was a 40A and I replaced with a PDI 45A (only because RV dealer only had a 45A on their shelves). 40A to 45A was a simple in and out with no wire upgrade changes.
For your RV and with no "dramatic" additional 12V upgrades (above factory build), then simply change with same size. Or, maybe 5 Amps more. Any larger upgrade would be a waste. And if doing 2+ size upgrades, connected wire might need upgrading as well.
Hope this helps...
