Vehicles suitable for a Watling Alko towbar

There is a huge range of vehicles on the market that have either a complete Alko chassis, or a reinforced Alko or SMV chassis extension. To list them all here would be an impossible task. However, below are some guidelines that will help you identify the chassis that your motorhome is built on, and therefore establish if this system is for you. Many individual vehicles are listed in our price list.

Full Alko Chassis
A chassis cab where the original box section chassis has been cut off at the drivers cab and replaced with a galvanised channel chassis (usually with large holes stamped into it) from the drivers cab to near the rear of the body. A failsafe method of determining this chassis is to look at the rear suspension. All full Alko chassis replace the original leaf spring suspension with a torsion bar system. So, if your vehicle still has rear leaf springs, then you do not have a full Alko chassis. A large number of Motorhome builders use the Alko chassis base for part of their range and some of the more common ones are as follows:

Autocruise, Autotrail, Bessacarr, Burstner, Dethleffs, Hymer, Knaus, KonTiki, Laika, Niesman&Bischoff, Pilote and Rapido.

Reinforced Alko and SMV chassis extensions
These are becoming more common on many brands of motorhomes. In this case the original Ducatto, Boxer or Transit chassis is kept and the leaf springs remain, but a reinforced or heavy duty chassis extension is bolted on. By and large, this type of extension is only available on motorhomes manufactured from 2007 onwards. Reinforced Alko extensions are found on all Swift Group motorhomes from 2007 (new shape Ducatto/Boxer cab), and on Autocruise vehicles from 2009 onwards. SMV chassis extensions are used on a variety of makes and models, seemingly with no pattern, and so should be treated on an individual basis. They are often recognised by a plate or sticker on the galvanised section with the SMV logo on it.
