I recommend using the TorkLift GlowStep Camper Scissor Steps w/ Landing Gear - 4 Steps - 20" Wide - 375 lbs # TLA7804-8000. These are a 4 step system that has glow tape on the steps to help with visibility at night, and the adjustable landing gear help stabilize the steps on un-even ground and they'll work for entry heights between 31" and 42" tall. These aluminum steps are light weight and easy to move up and down, as well as remove during travel, so they're perfect for truck campers.... view full answer...
