I purchased this ladder to use for my overland trailer/roof tent. It does the job perfectly. I didn't need the length I bought but I rather have too much than too little. The sections extend, and lock as they should. They hold my weight just fine (6'2" 260lbs) and collapsing them (carefully) works great so far. Hoping to get many years of use out of this ladder. I would recommend this ladder, absolutely.
