As noted elsewhere in forum, I purchased a 79 Biggar
sight unseen and used it for work summer and winter.
The floor was lumpy when I bought it. Which I attribute to lack of caulking maintenance. The belly was holding water draining in from around the windows! I could park on a slope and watch water drip out the frame openings after each rainfall. So I resealed the windows
and belly band hoping for the best. After a year, the floor stayed lumpy. I assume the long term absorption of water from underneath caused the plywood to swell and distort. It wasn’t soft, just full of undulating ripples.
I saw increasing evidence of movement at the cabinets each time I moved camp. I thought it may have been due to the old torsion axles being firm. Reducing the tire pressure helped keep the drawers from bouncing out, but the panel edge trims kept shifting and kitchen counter still showed signs movement at the edges.
Eventually, I checked out the frame by using a 5” hole saw under the benches. The frame was rusty, but sound. However, the gussets (standoffs) extending from the frame to the exterior were rusted out – I could put my finger through them! I’m sure that everything along the perimeter of the floor was depending on 3/4” plywood to support its weight
. My assessment was that without repairs, my Biggar
would be unsafe on the road.
Without frame repairs, it would only be viable as a park model. The only way I could see to access the frame would be to gut the trailer. Not having the resources of time, money and space, I parked the Biggar
Eventually took a lowball offer from a guy who thought he could fix the frame. His plan was to cut off the belly and work from underneath; but whatever he did, its his trailer now. I sold
it with full disclosure about all its issues.
That was my Biggar experience. The double walled trailers are comfortable in a wide range of temperatures. The double walls also made it very hard to assess the frame. The frame might have been alright if the belly had drain holes and/or caulking maintenance. If someone says they fixed it, ask for pictures. Caveat emptor.
Beyond the sour grapes of buying a rotten trailer for a steep price andselling low. I appreciated my time working out of the unit.
The wet bath was nice to have, it was compact and functional. Only skinny folk can enter the bathroom when the bed is set up. Possibly because I was using a twin size mattress.
The toilet is impossible to replace with one of the same height, and spare parts are unavailable.
The shower does not drain to a tank, it drains into the dump pipes. I used a catch bucket rather than drain onto the ground.
Ventilation was great! It cooled quickly whenever I opened windows
for a cross draft in summer. I put in a maxxair fan to have more airflow options.
I really admired the amount of fiberglass interior. The dining benches and cabinet bulkheads were all molded fiberglass. So were all the cabinetry faces and bathroom door. There was abundant storage for one guy, and it didn't feel crowded the occasional time I had a helper for a week.
In the winter, I ran dry tanks and kept a bucket under the kitchen sink for washing and cleaning. I kept a porta-potty in the wet bath. And I splurged on a rotary dehumidifier. It was a good investment. The rotary style works well in cooler temperatures. I think the added air circulation helped with winter comfort. And between cooking and sleeping, I was pulling a litre of water from the air each day.
I covered all the windows
with a layer of light
foam (laminate flooring pad) and a rigid insulation panel on the window by my bed. It would have been nice if the windows were double glazed. Any frosted glass had window coverings pulled back during the day and were defrosted with the dehumidifier.
The double walls of the Biggar had fiberglass insulation batts between them, and its little furnace
kept the trailer comfortable. I kept a tin deflector in front of half the vent to prevent air blowing in my face while I slept. I have since discovered that -20 Celcius in a stick and tin unit feels like -35 Celsius felt in the Biggar.
