Slanted plane sketching problem

Hi! I'm basically a complete Onshape beginner, so please bare and be patient with me.
I am trying to create a tape dispenser (pic) in onshape, right now working on the body. I've managed to make the bottom part of the body, on which it can already be seen that the front and back have different widths, and the bottom and top face of this part of the body are also of different sizes so the sides of the take are slanted. I created this part using the loft freature.
I then wanted to create the top part of the body somewhat similar; using the left feature since the sides are once again slanted to create a big block (pic) and then use extrude remove to create the curve in the top part of the body. However, as the sides are slanted, onahape doesnt allow directly sketching on them. I also tried to make a plane that would be the same as the side. However, as the side is warrying in with from front to back, and therefore also slanted at different angles as the top face is also of different length, not even the three point plane feature can fit a plane properly; it is always slightly off (pic).
As such, I am wondering is there another more efficient way I could approach the making of this part of the tape dispenser? I know this is a very vague question but I dont have anybody else to ask, and my question is so specific I don't know how to find something similar online. Any little tips, tricks or just a pount in the right direction would be a massive help. Thanks so much for your help.

Looks like you could just sketch on the Front plane and extrude in both directions.
I would approach that with some well placed planes at the ends, and sketches on each plane then loft the two sketches together. then look to extrude cut the top profile and maybe a chamfer on the bottom back corner. I'm sure it could be done with a bunch of simple extrudes and cuts as well by making a simple block and then extrude cut each face away as needed..but it looks like it has a taper from front to back so that is why I mentioned loft.
