Pulled the Apache outside so that it could be fully raised, the only way to reinstall the galley tops, and test the water system (with the sink upright).
Galley tops were a bit fiddly to get the joint between the two pieces to be thin/narrow and even. Cannot explain why this was necessary since no major changes were made to the tops when the laminate was replaced.
Water system testing was also interesting. The pump puts out an amazing amount of pressure, so larger and tighter hose clamps were necessary. Once done, the pump pressure was reduced a bit. I had wired in a manual “bump” switch that bypassed the pressure switch in the pump, thinking that if the pressure switch failed or became intermittent then the bump switch would still allow water to be drawn. That may prove unnecessary and the bump switch was stowed in the utility closet. May need it some day but not now.
The sink drain… didnt. I thought it might be plugged but it was clear. FINALLY realized that, like house drain plumbing, in order for water to drain out, air must be let in. Think vent stacks through the roof. So I plumbed in a Tee fitting right next to the sink drain and ran a hose to the top underside of the countertop and out the back of the galley cabinet. Now the sink drains as it should.

While the Apache is outside it rained several times. Most of the previous leaks have been remedied with new bed end seals etc. However, there was still small leaks under the bed end windows. Suspected cracked ABS around the window frames. Back into the garage it went so that repairs could be made out of the continuing rainy weather. I pulled the front bed end window out and, yes, cracks in both lower corners.
Those will be repaired with ABS grid and LABS.
While in the garage, I installed a battery disconnect switch, which essentially disconnects the batteries from the camper in case of fire, electrical issue or whatever.

Other minor punch list items addressed:
Rear interior ceiling panel had become dislodged and sagged. I trimmed the backing insulation foam, reinserted in its rear channel and wedged slime shims at the crossbar rib.
The fan was found to be not working. Replaced a blown 5A fuse. No idea why. Has not been a problem since.
While the camper was outside, and ALabama being Alabama in the spring, the road cover collected a lot of water in the “duck pond” areas, which eventually turned to muck. Once the camper was inside and deflated, I tried cleaning with Simple Green. Somewhat effective. But found that Publix “Cleaner with Bleach” was much more effective, using a purple scotch bright pad. After it was clean and dry, gave the top a coat of liquid wax (“Lucas Slick Mist” from NAPA), thinking that future cleaning might be easier.
