The ladder is attached in 3 places, one screw from the backside of the rail on each side top and one screw into the bottom side at the floor into the frame next to the bathroom wall. It is very firm and I have no reason to remove it, the ladder never seems to get in the way.
The leak sounds worse than it is. Windows in campers sweat too and create more moisture in the window frames than that little leak. I agree if the roof leaked I would be upset. If the rain is going to be real bad then maybe I shouldn't leave the slide open during the storm. If you can live without a slide I would but towing with the Ridgeline and what a slide offers in size makes it worth the extra maintenance required in my opinion.
The Ridgeline tows great! The 235 is right at the edge of the limit but I would say get the most that you can. The tow is the least part of the trip to me. You get in the right lane and cruise to your site and then play. Our camp runs will average a days drive. The Ridgeline is rated at 600 pounds on the tongue and you can weight and balance the trailer to stay at about 480 and the unit will pull great.
is for storage , when we travel we don't always take everything in the pictures and we move some of that stuff into the back over the axles to balance the trailer for towing. We won''t take the adult bikes anymore, we never ride them. We like to hike!
Good luck with your purchase!
