If you're only or exclusively considering a telescoping ladder, then the only difference, as Camp_CA
has said, is that the Lippert On-The-Go Ladder is pretty much charging $163 (!!!) for that ability to secure the ladder in place with the little hook tabs that fit into the receiver (See HERE
for the illustration).
Essentially, the EXACT same ladder without the little hooks can be purchased through Amazon for $86.99
12.5FT Telescoping Ladder, Telescopic Extension Ladder - through Amazon $86.99
That's a difference of $162.96 for a ladder that is almost identical and with pretty close to the exact same specifications as both:
* extend to 12' 6"
* are rated for 330 lbs.
* have a total weight under 25 lbs.
* have a fully retracted height of 33.5"
If it were me and i wanted a telescoping ladder (because of limited storage space), I'd go with the one without the hooks to save $162.96 as I could still access the roof without having to hook the ladder into the receiver. If you feel more secure using the receiver and you think that ability is worth the extra money, then get the Lippert.
Or if you have room to store an articulating ladder, I, like Ray,IN
, would prefer one where I could also use it as a step ladder.
