1. What is your recommended type of in Truck bed system for towing? (I have read there are several options)
Two main types are the
traditional 5th-wheel hitch with a large bearing-plate on top, and the
Andersen hitch with a ball-connection.
Both of those types can be further subdivided into those mounting to "bed rails" or those mounting to a 'gooseball'; the former rails stay in your truck bed when the hitch is removed, the latter can usually be removed from the bed when the hitch is removed. Both require robust steel assemblies installed between the underside of the truck bed and the truck frame.
Some (IMO) generalizations
Traditional 5th-wheel hitch
- tend to be rather heavy, impacting both useable payload and ease of removal
- some can be 'noisy' due to the number of separate articulated connections in the hitch
- no safety chains required in any jurisdiction
Andersen
- Probably the lightest hitch available
- quiet because the only moving connection is the closely-fitted ball
- safety chains required in most jurisdictions
Rail mount
- tend to be lighter assemblies than removable gooseball mounts
- tend to be less expensive than a removable gooseball mount
- present a permanent ~3/8" high 'obstruction' at two places across the bed when the hitch is removed (many folks don't object to this)
- wide variety of 'bolt-in kit' brands available to fit most (but not all) truck make / model / bed configurations
Gooseball mount
- tend to be heavier assemblies than rail mount systems
- tend to be more expensive than rail mount systems
- with the gooseball removed, the bed is without any obstructions ('flat' like OE with nothing in the bed, desirable for some folks)
- may not be offered as a 'bolt-in' kit for as many truck models as rail mount kits
I mention and advocate the use of a 'bolt-in mounting kit' whenever possible, even if installed by a shop, because they are designed for vehicle-specific fitment and avoid drilling, welding. or otherwise altering the vehicle frame.
There's folks on this forum towing 5.0 trailers with every possible combination of the above and perfectly happy / enthusiastic about their choices. Much depends on your personal preferences, vehicle and / or personal-lifting weight constraints, how you use your truck bed when not towing, etc, etc.
I am among those very happy with the combination of a
B&W Turnoverball (removable gooseball) and the
Andersen Ultimate Hitch which mates to that. Key attributes of that system which I like for my purposes
- light lifting-weight of the components I remove when not towing
- my truck bed is perfectly 'flat' when the hitch is removed (no obstruction whatsoever for sliding items in / out of the bed)
The
e-trailer website is one you may find useful - you can enter your truck-specific data and see options for both mounting systems and hitches designed to work with that truck.
All just FYI, hope that helps
