The things that end a first trip early
Most first-trip problems are hookup problems: a sewer hose that doesn’t reach, a plug that doesn’t fit the pedestal, or no way to level the rig. That’s why hookups and leveling come first in this list – the kitchen can be improvised, a 30-to-50 amp adapter can’t.
Keep the drinking-water hose separate
Store the drinking-water hose in its own bag or bin, never with the sewer gear, and cap its ends. Many RVers use a white or blue hose for water so it can’t be mixed up.
