Thanks for all the interest in the project. Things are (slowly) moving ahead. Here are pictures ofstart of the bedroom and installation of a large compartment door under the bed to access barbecue and other goodies.

We will also have two drawers at the side of the bed that will open in the doorway about 24 inches long

Fred: The panelling I chose for the walls is vinyl coated. I thought it work best for the moisture. All cabinets will be oak with a varathane finish.

I once tried to get a trailer manufacturer to increase the size of the gray water tank and reduce the black water tank. They said that the engineering people would not allow it because the locations and sizes were already determined along with the locations/weights of all other aspects of the trailer and changing something could screw up the balance too much. And even more importantly, they were not about to go over the engineering analyses of sheer and bending stresses required to make any change to my trailer.

That said I salute you and your project; I love it when people think outside the box (or trailer). And yet I wonder how confident you are about the stresses on the frame with more weight and the relocation of weight from the original?

Cheers John

I've been following your project with much fascination- You've got a lot of guts!
Makes me look at my Trillium with a speculative eye...
I'm with John- I'd like to hear more about what you did to the frame re. extra stresses, etc.-did the extra 44 inches in length require "beefing up" the frame in any way? Or was the original tubing/angle iron/whatever you had the right size-weight to begin with?

Thanks!

Francesca

This is the most amazing build I have ever seen! I have had dreams of stretching a 13' Scamp in to a "17' Boler". But I figured I was nutz! I can't wait to see the final product. You truly do amazing work!

John and Francesca

I have had a few questions about the frame and weight. the original trailer weighted 2300 lb The old paperwork from the trailer says the trailer weighted 1850 but I weighted empty. Anyway 2300 is not to bad for a 3500 lb axle ,but now I have two, I am good for 7000 lbs

Trailer should weight in at about 3300 to 3600 [ With 4 6 volt batteries ]

All my tanks are now going to be under the trailer between the axles ,my batteries , fridge,waterheater, oven, the main weight load will be on the axles .I was going to put my fresh water under the bed but I found a better tank that will fit under. Up front is all bed and storage under it. I will have to watch what I put in there so there is no real jump in tongue weight

Will have more pics soon

Thanks Ken

You have the right idea -- locating as many of your big tanks between the axles as you can and the fridge/oven as close to being above the axles as possible. Of course the other important weight is the rule of thumb of 10 to 15% of the trailer weight on the hitch. Good luck to you!

Cheers John

Hi, Ken

Thanks for the update!
I can't tell by looking at your early pictures- did you have to reinforce the tongue in anticipation of the greater trailer/tongue weight etc.?


Thanks

Francesca

Hi Francesca

I asked about the tongue strength when I had the frame modified and the shop that did the work said it was strong enough without any mods.

This is the second trailer they have done for me, the first was good.I had it for years with no problems.

It is 4 x 2 inch tubing frame, Some trailers weighting over 5000 use the same size tubing should be plenty strong.


Thanks Ken

Francesca do you have any pics from the side, looks very interesting. Does the boat trailer just roll up on ramps or is it loaded on

Thanks Ken
