Trailer size to cabin size relationship

Hi there,

First timer here! I am embarking on building my first teardrop based in Auckland, New Zealand.

I am in the process of getting quotes from local trailer manufacturers to build the trailer as I am mostly familar/comfortable with woodworking than steel work and I have a basic question about the relationship of the frame to the teardrop.

I am wondering what is the recommended overhang (or not..) from the frame to the trailer. I am leaning towards having a 50mm overhand on all directions mostly to allow me to get started on the build as the trailer is being built and curious if there's a rule somewhere about this relationship.

Here's some images of where I am at with the design.

The dimensions I have currently are:
Trailer Frame:1452x2600mm
Teardrop Base: 1552x2700mm
Cabin size: 1600x3200mm

Thanks in advance look forward to sharing my build journal!

I build a chassis frame that is 59.5" (1511.3 mm) wide for a 60" (1524 mm) cabin. This allows for the cabin to not sit on the trim, if sheathed with aluminum.

And I build off the chassis:



Your galley is similar to what I build, but my countertop transitions into the lower shelf. It works well. (The bulkhead is two-piece.)

Hi Tony thanks for your reply!

I actually bought your book a couple of weeks ago and has been of great reference and inspiration!

The reason I was wondering about the frame of the trailer is that given the round shape I want to achieve I want to de-emphasize the trailer frame given that I think it might look weird and it's sitting on the trailer.

I thought about dropping the walls to cover the frame as well but that would really impact the interior cabin height.

As per the bulkhead, yeah I thought about that as well but wanted to keep the height as close as possible to 920mm and have more leg room at the bottom for a thicker mattress, looking into options for mattresses atm as there aren't as many options as in the States here

It sounds great. I can feel your brain cranking.

and have more leg room at the bottom for a thicker mattress,


We have an 8" mattress. 5" of foam with 3" of memory foam bonded to it. Even with a down quilt, it gives us plenty of room for our feet and the heater vents. For us, with that mattress, and covers, the 22" works.
