I just finished a major part of my 1986 Scamp
So far I have removed and modified the front of the frame extending the side rails to where the turn in is just past the cabin.
This gives me room to move the side bath to the front between the frame sides. I have a bath floor with the dropped shower pan and a toilet with the black tank under the floor.
The floors have been replaced with 3/4" exterior plywood covered in 6.5 oz. fiberglass cloth and epoxy.
Before installing the main floor I installed the new Flexiride 3500 lb axle
(derated to 3000 lbs to improve the ride harshness).
I installed the axle
to place the centerline of the wheel in the same place as the AL-KO 2500 lb axle
Since I had to buy new wheels anyway since the brakes
are not available with 4 lug hubs for the Flexiride I bought 14" 205-75R 14 Kenda tires
and wheels at Pep Boys for $94.00 each (3 with the spare).
I set the ride angle at 22* down so the ride height is greater from this along with the larger diameter of the tire/wheel.
While the wheel is centered in the wheel well the actual cutout of the shell is a little close to the fiberglass at the front of the cutout.
I think I will rework wheel cutout for a little more clearance.
I would lower the axle if there were a little more clearance over the tire where the fiberglass wheel well if flat instead of curved to match the rest of the tub.
I changed the tires
and wheels since these Scamps seem to be heavier than the original ratings. The original tires
were rated 1360 lbs or a total of 2720 lbs. If the axle rating of 2500 and maximum weight
were correct then these tires would be marginally adequate. The 185-80 13 are rated higher, but still not comfortably higher for 3000 lbs rating of the new axle. ( the new axle was made with shorter rubber encapsulation of the rotating stubs on the 3500 lb. base setup.
Has anyone else fitted 14" tires and how was the axle setup? I assume that the Dexter or AL-KO axles with 22* down would fit like my setup.
If I rework the wheel tubs to have round tops then I might move the trailing arms up a little to lower the trailer for better handling while keeping the 205-75R-14 s.
If I were to redo the axle I would mount it about 1 inch towards the rear (maybe not since this would shift the center of gravity). I would also order the axle with the face to face distance of 63" instead of the 65 inch of the original AL-KO with the 13" wheels.
Also I found that the frame was 48 1/2" outside dimension where at the front it was 48" (Oh well!). Also the Flexiride axle delivered stock the bolt on flange vertical with mounting holes is on the inside rather than outside. Mounting would have been easire if I had got the 48 1/2 " right and if the larger mounting flange were on the outside. I think you can specify that a different mounting flange that matches the AL-KO / Dexter mounting. This was not a problem not having the same bracket since the trailing arms are 2" shorter and the axle has to be relocated to put the axle hub centerline in the correct place.
The 14" wheels and tires really fill the wheel well, but I think there is enough clearance.
