We have a 2014 Bighorn 3570RS. On the front of the unit where the front body panel is attached (this part has the door for the storage compartment where a generator can go) the daylight shines brightly. The first time we towed in the rain, quite a bit of water got in the compartment. Should it fit tight? There does not seem to be any play or room to make a tighter fit. Everything seems tight. What would be the best thing to use to seal the gaps? My second question is I have noticed a small white plastic elbow under each main slide. The first time I retracted the left side a bunch of water came out of it. What are they for? 3rd. In the front storage compartment is a large crank type of tool. It has a hole drilled through the end of it. What is it for and should there be something in it?
