P.s. on main pic, i circled cracks in yellow
Ramon, I might have some bad news for you. You may have what I call front curb side sag. Typically I see this when there is a rip in upper front corner of the door, (like yours) and the lower back corner of door, (unlike yours). Think of it like the rectangle of the door is being pulled into a parallelogram. The other two corners would be in compression. I have never seen the damage that your trailer has at the bench height. I will have to think about that. There are a few things to look at. Take a straight edge, a 4' long 2x4 will do, as long as it is straight. Put one end on the floor at the door of your fridge
, the other end toward the trailer door. Is the floor sagging toward the trailer door? Also, stand on the tongue of the trailer and look down the flat section of the roof. Can you see a high point where the closet is? If the answers to these questions is, yes then I think the section of your trailer that is forward of the door is sagging. The only thing that I can think of that would cause this is the plywood in your floor has rotted. Look in the front gaucho. What is the condition of the plywood on the floor of the gaucho? Another inspection point for the plywood is under the fridge
. You would need to remove the fridge
to inspect the plywood under it. If the plywood in the floor is badly rotted, this is bad news. The repair for this is difficult, and there is no agreed best way to do it.
I have put lots of thought into this, and the plan that I have requires that the coach be removed from the frame, then cut the bottom of the trailer off, from the step above the axle
to where the plywood ends in the front gaucho. On the sides I would cut the bottom of the pontoons. This may not be wide enough, but what is left of the pontoons can be spread as required. The main problem with this approch is that the fibreglass on the floor and the bottom of the trailer are likely glued to the plywood. This would make removing the bottom of the trailer, in one piece difficult.
Another approach would be to cut just the floor of the trailer, after removing the fridge, and furnace
, (if you have one). Remove all the fibreglass that is flat to the floor, right up to the door. Leave the kitchen, closet and gaucho walls dangling. This would allow you to remove the rotten plywood in the floor and reinstall new ¾" plywood in sections that are as wide as the hole for the fridge. Each section, once flat would be pushed, (hammered) to the back, up to the step in the floor, (note that the wheel wells will make this piece shorter) and another forward under the gaucho, to where the front starts to bend up. This would probably involve more than one plywood board in each direction. Before each piece was pushed, I would lubricate the path with a liberal application of some slow setting epoxy. Slow setting so that you have time. The last piece would fit between the front and back pieces, ideally the width of the fridge hole. Then fibreglass over where the floor was, connecting the bottom of the kitchen, closet and gaucho to the floor.
It should be noted that the sag should be corrected before any of this is done. Before you pull the coach from the frame, I would support the bottom of the coach, where the sag is. Pushing it up till the floor of the trailer was flat again, for at least a month. Fibreglass is plastic. That is it will retain the shape that is pushed into.
It should be noted that I am looking for a Trillium 4500 with this issue, preferably a front gaucho version. However I would not replace the plywood with wood, I would use pultruded grating:
This is 1” thick vs. ¾” thick, so my floor would go up ¼”. It is also quite expensive. Material costs would be over $1000 Cdn.
