Richard,
I transport every day ....
I just dropped off this 1930 Model A steel body coupe near Philadelphia, PA ...
Several years ago I custom designed my car hauler to accomodate vehicle
and parts hauling - experience towing over a few hundred thousand miles
will benefit my new trailer being built later this year ...
What I have learned over the years from towing an enclosed trailer daily:
A square steel hand welded tube frame is the only way to go
The frame must extend to the outside edge of the trailer - no outrigger frame
Few manufacturers use this design because of expense - but it greatly reduces flexing
which is transmitted from the road and eventually breaks a trailer apart over time
Aluminum siding fastened w/o screws will (in time) separate from the frame
Have your aluminum panels screwed to the tube frame
A V nose is a waste of space - choose a flat front w/ coffin up top to help wind resistance
Spring axle - not torsion - torsion axles are not serviceable and must be
replaced if they break
Opt for a spread axle design where you have a triple axle layout
as far as space goes - but no equalizer between the leaf springs
Each leaf spring attaches to a hanger - this design spreads the
load out over a larger footprint and saves on axle & suspension wear
Extended tongue is a must - have the breakaway battery & any other
mounted items mounted on the trailer body & not the tongue so
you can not interfere w/ weight distribution hitch brackets you might need
Wire the interior lights separate from the tow vehicle running lights so
you do not need to be plugged into your tow vehicle to use them
Have the manufacturer weld a winch mounting plate to the trailer frame
under the wood floor - center it in the trailer
Install a 12VDC deep cycle battery in a battery box & have a charge
feed ran to your 6 or 7 way tow vehicle feedto keep it charged
Install a 12VDC electric winch w/ wireless remote adjacent to the battery
in the front center of the vehicle - I opted for a Badlands 9000 lb. winch
from Harbor Freight w/ wireless remote control to load & unload every
vehicle I haul - I never drive a car on or off my trailer
Consider rear barn doors instead of a ramp door - this will allow you
to load cargo w/ a forklift and save you from replacing an expensive
ramp door in a few years - ramp doors wear out because in the real world
you seldom load & unload on a level paved surface - the door can deform
I bought a set of 8 ft. aluminum car hauler ramps & a set of 5 ft.
extensions to have a usable loading ramp length of around 12 feet
This ramp set is rated for 5000 pounds per axle
This affords a very slight angle & allows me to load & unload
low clearance vehicles w/ease
Instead of a traditional side escape door - opt for an additional entry door
located on the curb side near the front of where your vehicle will end up
when located in the trailer - you usually can re-locate the standard entry door
included in most trailers at no charge
My trailer has 8 ft. barn doors which allow the loading & unloading of
additional cargo in front of the vehicle
On the trailer w/ the 1930 Ford for this trip was a snowplow blade
I dropped off today to Dave near Harrisburg, PA ....
If you PM or call me - I can tell you who
not to buy a trailer
from and
who I chose to build my next custom trailer ....
