Exelent choice. I have TPO roofing on my S&B flat roof here in Arizona. Installed in 1989 when TPO first became available and its doing fine. Our motorhome also has a TPO roof, no sluffing off of the top layer and no streaks down the sides.

I did. They want $4800 to do my 34' RV! That's crazy!!

WOW! that is a lot. I knew it cost but had no idea it was that much. If you are DIY, then I would look at the Rhino

Check coating it with EPDM Liquid rubber, check on here for several folks that have done so. It is a DIY product. Cost in hundred not thousands dollars.

This has my attention when I need to replace.

TPO is the tougher of the two materials, and does not have the sluffing off of the top layer as EPDM. There are several companies that sell kits for diy application. Dicor is one of them.
In an RV application there should be no need for seams.

I haven't used TPO in an RV application, although like you: ours will need replacing in the near future. TPO is the way I'm leaning as it's more of a resilant material compared to epdm. From past expierennce in commerical building applications I've seen the durabilty, but the installation is much more tedious than epdm.
EPDM is great but can tear more easliy than tpo. Unlike epdm tpo needs its seams welded with a special welding iron and rod. In your case depending on your rv size you might not need to worry about seam welding, but depending on your rv roof profile, you might have to miter some of the corners and then the seam welding would come into play
