Go with a 24 inch wide step for confident footing and 4 steps for a gentler climb that's easier on everyone, pets included. Install can be a direct swap, though you might need to shift mounting brackets or trim a threshold or screen-door lip on some older campers to get the door to close. For truck campers, attach the steps to the camper rather than the tailgate.
Start by leaving off the decorative roll plate at the threshold to lower the step plate. If you want that plate, trim the center section so only the ends remain. If needed, trim the threshold lip at each end to lower the bracket. If the screen door still hits, mark the door frame width at the step brackets and measure up about a half inch, then remove that section. The outer door may be tight but can close.
Mount scissor steps to the camper, not the tailgate. Curved tailgates don't provide a proper straight edge, and many remove the tailgate entirely. Verify you have a solid mounting surface on the camper's bottom edge and install the included bracket there. If clearance is tight, minor bracket placement adjustments may be needed for a snug, level fit.
A 4-step setup reduces the incline, making entry and exit feel easier and more controlled. It can help pets navigate the stairs with more confidence. If you're moving from 3 steps, expect a more comfortable rise between treads. Check your ground clearance and typical campsite height to be sure the lowest step won't contact the ground on uneven sites.
Often yes. Measure your existing step frame and bracket spacing to confirm. If the new frame is slightly different, plan to move or adjust the mounting brackets. Test-fit with the door closed to confirm clearance before final tightening. Install has been described as easy when the frame widths match, and still straightforward with minor bracket adjustments.
