Great, I'm feeling better about it again
Let's look at it this way, in a very rough estimate way:
Trailer frame alone weighs ~250lb
One sheet of 1/2 ply weighs 30lbs, I'm using less than 8 sheets in my build. That equals ~240lbs
One sheet of 3/4 ply weights ~50lbs, I'm using less than 3 sheets. That equals ~150lbs
One 2x2x8 furring strip weights ~4lbs, I'm using roughly 20 of these cut down to size. That equals ~80lbs at full length.
Those numbers on the high end equal 720lbs.
Then I have insulation, screws, glue, nails and all of that. I'll add 100lbs to be safe.
Now I'm at ~820lbs on the high side.
I've added some structural support to the frame, let's say ~50lbs.
Now I'm at 870lbs on the high side.
I need to install my doors. Those probably weigh about 30lbs a piece.
Now I'm at 930lbs on the high side.
I'm going to bedline the unit, so lets add 100lbs there.
Now I'm at 1030lbs on the high side.
My galley area sink, burner, storage and whatnot, plus 10 gallons of water, lets say another 100lbs.
Now I'm at 1130lbs on the high side.
Lets say I add a couple of AGM 100ah batteries to the tongue box, let's add 150lbs for that.
Now I'm at 1280lbs.
Let me add a roof rack and awning. Lets say 200lbs for that.
Now I'm at 1480lbs on the high side.
I can't image I'll be adding a whole lot more to this build in the future. It's built to serve the purpose of sleeping in. I have Cherokee Sport that's gutted besides the two front seats. I have a lot of storage in there I use for lots of things.
Just throwing some numbers out there to see what ya'll think.
