If you own one of my tents with the slide-out style ladder, you can easily upgrade to the telescopic ladder with basic tools. The telescopic ladder extends to 8ft which can eliminate the need for a ladder extension in most cases. Also this ladder can hold up to 300LBS and has multiple locking points to accommodate different vehicle heights.
Please note If you are replacing a ladder on the Upper Hutt or Penthouse XL model tents, it is not a direct fit. The mount brackets on the base of the tent need to me moved which requires drilling some new holes and basic tools.
