Could you tell me more about your inspections? What do you inspect? What do you look for? I would love to be able to make a jump forward in my understanding by learning from other peoples experience!
often places more physical stress on trailers used for this purpose than they are designed to withstand and over time this takes a toll on the unit. I've made some modifications over the years to facilitate off road use.
My first observation was that the suspension was usually designed for travel on flat surfaces like paved roads. Off road, with dips and uneven surfaces, the hitch and/or the rear bumper of the trailer could scrape on the ground, or worse still, damage the plumbing.
Some units have a height adjustment capacity on the suspension. I've also used spacers to increase the distance between the suspension and the chassis.
are suitable for highway travel but may not have the physical size or strength for off road use. Increasing side wall height of the tires and/or the wheel diameter will lift the trailer. I usually go up a size or two with the same wheels although I have also used larger wheels to get a higher lift. I like 6 ply or heavier tires because they are stronger and can withstand harder use. They are more economical over the long term as they last much longer. Maximum tire size is determined by the size of the wheel wells on your unit. Don't forget to allow for suspension travel.
Likewise, the axle
is intended for mainly highway use and is usually suitable for this purpose. It will support the trailer and accommodate sway and suspension travel under these conditions. Off road suspension travel is much greater when the trailer bounces and this puts more stress on the axle
. In addition to the weight
of the unit the axle must also accommodate the inertial force when the suspension flexes. That's why an axle with a higher weight
capacity will be more durable.
A higher weight
capacity axle WILL NOT make the ride stiffer or the trailer bounce more. These factors are controlled by the stiffness of the suspension and tire pressure.
Lifting your unit will raise its center of gravity and may decrease stability, especially in cross winds.
I usually inspect my unit before each use. I look for things that can go wrong and make sure they haven't. I start with the hitch, tongue, lights
, tire pressure etc. I look at the suspension for damage etc. which can often be indicated by the way the unit sits when parked or towed. It becomes a matter of learning how your unit should look and checking to ensure everything is intact.
