We just boondocked for 4 days in Prairie City for the eclipse. The 400 watts of solar on the rear shell and the Dometic compressor 'fridge worked well. If I have my charge indicator set right, we took 1/4 of the pair of GC/2 batteries to get through the night with the 'fridge fan running (perhaps irrationally I figure moving air across the coils will result in a net saving) and some use of vent fans in the evening after sundown. We were always fully charged before Noon and thus had no problem running both vent fans and the bathroom fan all day.
To boondock well, the TM could use a larger fresh water tank and gray water tank. Two tall people did fill up the Thetford in 4 days, this can be extended to 8 days if you want to use a 6 gallon sewer tote, which I ended up doing just to reach the dump station without moving the camper at our next destination.
