Praise God you guys are safe. Just a practical thing: With caravans, trailers etc....NEVER ignore or delay checking out any unusual sounds, knocking, rattles. Maintenance and vigilance is vital. Remember that the Holy Spirit will use others and also an inner witness that you may need to stop and attend to an issue to do with security or repairs etc. Obey immediately. Get into the habit of doing a set-up and pack-down checklist that includes checking oil, fluids, brakes, drainage, electrics, batteries, tyres.....everything. My family avoided some serious problems doing this. And NEVER drive tired!!
