Group reqests here.
Twin Axle ( and use T/A to get overall height down and COG )
LIGHT WEIGHT. (Caravans have got to heavy. Light weight = less fuel)
Aero Shaped front to use more of wasted A frame space and fill the gap between the tow car to improve aerodynamics and aid fuel consumption.
Composites and honeycomb modern floor for strength, rigidity and durability.
Alloy/ GRP / composite body work shell and roof. With modern two pack bonding systems to guarantee 25 - 30 year life and water proofing.
Stainless screws if they have to be used.
LED running lights. (Truck builder friend is using slim neat very bright LED with very high mileage long life, no need to change bulbs and let water in with big holes to take old fashioned lights)
Plenty of windows with flush finish to improve the looks and aero's. Roof to include aero flairings to improve airflow over large rooflights, vents and aerials. Space and connection point for Solar Panel.
Roof should be able to take walking on and have snow loading rating.
Plenty of windows and large roof lights to front and rear.
Interior: Lightweight alloys. plastics and composites. Frameworks of fittings to fit to flooring and wall fixing points (no screwing through carpeting) allowing for a variety of interiors or updating or changing the layout in the future.
LED lighting. Silent running water pumps. Option of compact bathroom or large. Side bathroom or end bathroom, twin dinette.
Fridge that works in continental hot weather or has fan vented air flow to cope with hot climates.
Blown air heating and cooling, air con uses to much power for many sites and is to noisy for neighbouring caravans. Cool silent blown air for night time use is a must in hot climates.
In built jacking for levelling and wheel changing.
360 KG load to cover motor mover and what modern day caravanners carry in the way of Entertainment and Cycles etc.
Make it - Light weight, Strong and Watertight and Aerodynamic with interior flexibility.
We think that if caravan interiors were flexible an updatable with a good durable secure shell and chassis a manufacturer would retain customers and a steady flow of business, as families and use changed the caravan could be changed inside to suit the family or couples needs. Rather than lots of different caravan shells. Fixing points to take modular fittings to personalise interior layouts and updates.
ps
Just forget ABS panels.
