I have never been comfortable using the rear ladder to access the roof on my 2011 Big Country 3250TS. However I thought it would certainly support two bicycles on a Camping World rack. Wrong! On our trip to Florida all six brackets on the rear cap loosened and all screws attaching the brackets to the frame were broken. Luckily we did not lose the bikes on the interstate. Next time I'll read the Forum posts before trying something different.There was fair warning posted there.
