HOW TO SELECT THE PROPER TRAILER
The most important aspect in selecting the trailer you need is weight capacity. The proper trailer for your boat will carry the fully loaded weight of your boat plus approximately 10% overage for safety purposes.
To determine the weight of your boat add: the published dry weight (plus engine or engines if outboard powered), gas (gallons x 6.5 lbs) and water (gallons x 8.4lbs.), trolling motor, batteries, and loose gear. Plan ahead and add for camping gear if applicable! Compare the loaded (wet) weight to our available trailer models adding the 10 percent safety margin.
For example: 2200lb. Hull + 400lb. Outboard + 200lb. Fuel + 100lb. Batteries + 200lb. Loose gear = 3100 pounds.
The 3100-pound capacity trailer will carry the example load but will be at maximum capacity all the time. Adding a safety margin means that this load is more appropriate on either our 3700-pound capacity single axle or our 3500-pound capacity tandem axle model.
King Trailer model numbers correspond to their load capacity to make selecting the proper trailer easy.
Your required length should take into account the overall length of the boat and bow pulpit without adding for swim step. Our trailers will provide ample adjustment for length unless your boat is unusually light or heavy for its length. Check our specification page for Bow Eye to Transom Min. and Max. to confirm proper length for your hull.
Brakes are required on many trailers although laws vary from state to state. Please refer to your dealer or state trailer law websites for your local requirements. It is the sole responsibility of the owner to comply with all applicable laws. Check state laws here: http//www.rvsafety.com/state.htm
ROLLERS OR BUNKS?
Each system had its own advantages. Roller trailers will roll the boat off and on in lower tides or shallow ramps; bunk trailers will support more area under the hull. King Trailers new Glide King custom poly bunk surface provides the support of bunks with the launching and loading ease of rollers. Your dealer or the boats' manufacturer can assist in weighing these and many other reasons to select one type of trailer over the other.
Once you have decided on the correct capacity, length and type of hull support the trailer must be fitted to the hull. This is often a relatively easy task, but since correct hull support and balance are critical for your hull and your safety we recommend the experts at your dealership perform the adjustments. Most dealers will add a minimal hourly fee or flat rate that is well worth the cost. Adjustment is not available through the factory.

BEFORE YOU TOW BE SURE THAT:
- You have read and understand the information in the handbook supplied with your trailer.
- Hitch, hitch ball, and coupler are rated correctly for the weight of your rig.
- Coupler is latched and safety chains, lights, and brake emergency cable are secured.
- Winch strap is snug and bow tie-down secured.
- Tie downs are snug and buckles are protected from marring the boats finish.
- Tires are properly inflated and lug nuts torqued to recommendation.
- Re-torque lug nuts after first 50 miles and any time tires have been removed. All lights are working.
- Trailer brakes (if applicable) have ample fluid and are responding.
- All fasteners are in good condition and tight.
- Spare tire (recommended) is properly inflated and all tire changing tools are available.
- Insurance coverage covers the trailer and boat too.
- Know the maximum tow rating on your trailer. Overloading is dangerous, illegal, and the drivers responsibility!
- It is highly recommended that you carry a spare tire. Remember the tire changing tools for the tow vehicle may or may not work for your trailer.
- Be aware of the importance of Tire Safety. Read important information on maintenance and safety at: www.nhtsa.dot.gov/cars/rules/TireSafety/ridesonit/brochure.html

MAINTENANCE AND STORAGE
Your trailer should be inspected periodically for signs of wear, corrosion, and fastener tightness. In saltwater conditions the trailer should be flushed with fresh water after immersion and special care should be taken around brakes, winches, tongue jacks, and couplers, to slow corrosion and fight salt buildup. Bearings should be lubricated with quality boat trailer bearing grease and re-packed before storage. If water is present when adding grease to your bearings shorten the interval between applications. Couplers should be lubricated and checked for snug fit around the hitch ball.
For long-term storage, clean the trailer well with soap and water. Winch and tie down straps should be relaxed slightly. Winch strap/cable and tie downs should be inspected for wear and replaced if necessary. Bearings should be serviced and checked for adjustment. Brakes can be cleaned and coated with light oil in non-critical areas. Jack up and block the frame to relax the load on tires and suspension. Cover tires to avoid ultra-violet degradation. To help the boat drain, store with the trailer tongue slightly elevated and the drain plug removed.

LAUNCHING AND LOADING
Prepare to launch by removing rear tie-downs and motor supports.
Do not disconnect bow tie-down or winch.
Unplug trailer lights.
Prepare dock lines, fenders, etc.
Be certain boat drain plug is installed!
Back down ramp until engine is submerged enough to start.
Put vehicle in park (or low gear on manual), set parking brake and chock rear wheels.
Using recommended procedures, warm up boat engine.
Disconnect winch and safety chain and launch boat.
Submerge trailer until boat contacts the trailers bunks or rollers before it is half way on.*
Park and set vehicle as above.
Bring the boat to the trailer as centered and square as possible.
Winch or drive boat onto trailer.
Use caution to raise prop so the engine does not strike submerged objects.
Winch snugly into bow stop and secure safety chain.
Proceed to tie down area away from ramp and secure boat to trailer.
Wash and flush engine, boat, trailer, and trailer brakes (if applicable) as soon as possible.
* Note when loading:
If the trailer is overly submerged, the hull will not guide to the center. Adjust your depth so that the boat contacts the rollers/bunks in the back one-third to one-half of the trailer. As a guideline, try submerging the trailer to the top of the rim at waterline (top of the front rim on multiple axles). Adjust the depth if necessary on subsequent loadings and repeat the depth that works well by putting the waterline at the same point on the trailer each time.

King Trailer warrants each new trailer to be free from defects in materials and workmanship for a period of three years from the date of purchase. King Trailer shall repair or replace, without charge, any parts found to be defective because of imperfect workmanship or materials within a reasonable time after the trailer is returned at purchasers expense to any authorized King dealer or distributor.
This warranty is extended to the original purchaser only and does not extend to any other persons to whom the trailer may be transferred.
Provisions of this warranty shall not apply to any product which is found to be modified or altered in any way, nor shall the warranty apply to any defect or malfunction which was caused by damage, unreasonable use or failure to provide reasonable and necessary maintenance. The warranty will not cover damage caused by overloading the trailer beyond stated capacities, or the use of improperly installed weight distribution hitches in conjunction with hydraulic surge brakes. Due to the highly corrosive conditions a trailer is exposed to, rust formation is not covered.
This warranty does not cover winches, lights, couplers, brakes, tongue jacks, springs, axles and tires or wheels, as these items are warranted separately by their manufacturers. Wheel bearings are covered for 90 days from date of purchase only.
ANY IMPLIED WARRANTIES, OBLIGATIONS OR LIABILITIES, INCLUDING BUT NOT LIMITED TO, AND IMPLIED WARRANTY OF MERCHANTABLE, SHALL BE LIMITED IN DURATION TO THE TERM OF THIS WRITTEN LIMITED WARRANTY. Some states do not allow limitation on how long an implied warranty lasts, so the above limitation may not apply to you.
The use of any unit as a part of a rental fleet, or used for commercial purposes, voids this warranty. The following are exclusions of King Trailer warranty: Loss of time, inconvenience, towing charges, travel expenses, lodging, telephone, gas loss, or damages to personal property or loss of wages. This warranty is intended to comply with the Magnusson-Moss Warranty Federal Trade Commission Improvement Act and any provisions of this warranty or actions taken by King Trailer pursuant to this warranty shall be construed accordingly.
