tripplite inverts trip a GFCI but there is a work around
My Roadtrek 210P also trips shore power GFCI outlets. I trouble shot the issue to the inverter. If nothing is plugged in to the 3 inverter outlets in my rig the GFCI does not trip. I called Tripplite support and they were incredibly great...
Wheel Spacers
If your Dodge Van based Roadtrek handles poorly check the track width of the rear vs front. On my 1999 170 the difference was 3.5 inches. I installed wheel spacers (1.75") and now the van drives great.
