Slumber Coach question

[Sierra Ray]

I'm almost done with my frame,but I've got to get some numbers together so I can layout the profile. I've downloaded the specs for the Slumber Coach, but I've decided to do the streched out version. I need to position the axle on the frame and do other measurements. How do I alter the numbers to fit my bigger version? anyone....angib???

are you just making it longer? or taller, too? this is a perfect time to loft [draw] the profile full size. if you don't have floor space, do it on a wall and then paint the wall when you've built the trailer. it will give you a look at what's happening before you cut wood.

it may be best to draw the original version first to see where you're starting from [benchmark] then pick the areas you are modifying. after those cimensions are decided upon, "connect the dots" with fair lines. use a thin stick [batten] and massage the profile until there are no hard transitions [bumps!].

good luck

Ray,

I suggest you stick with the same ratio of wheel position to overall length as the original as this will give you about the same tongue weight ratio.

As drawn, the Slumbercoach has its wheels 47" from the back of its 106" long body, or 44%. This position is well forward compared to other teardrops, but I think its longer 'tail' may be the reason.

So, for example, if you stretched the profile to 120" long, I'd put the wheels at 44% of 120" = 53" from the back.

Thanks guys, I'm going with the 10' x 5' frame. failed to mention...
I know if I stick with the 48" hgt it would look longer, but like you said I need to draw out a full size pattern. I've got 5 acres,but not very many flat spots.
Thanks Andrew, 44% it is. Thats what I was trying to figure out. Now to finish the gussets on that frame(pics later).

Ray,

If you are going for a 120" long body, you'd be better off making the frame a few inches shorter, as otherwise it's going to stick out visibly underneath the back of the body:



And of course if you shorten the frame by a few inches, you need to also take those same inches off the back-of-frame-to-wheel-centre dimension!
