Hello All

I am about to commence on this years project, a tandem off road pop top camper trailer.

I have purchased many of the components for this project including a tandem 2.5 tonne Simplicity Suspension.

The main body is 4.2 metres long which includes a rear section that folds down and incorporates a shower/toilet and entry to inside.
I have researched many options from hydraulic cylinders, 12v electric telescopic actuators, gear driven worm drives and every option comes close to approximately $4,000.00 for components.

Although the camper is expected to cost about $35K for components and materials, I cannot convince myself that it should cost $4K to lift the roof.

The roof complete with insulation, lining, retractable Air Conditioner and a 80kg tinnie will be approximately 225 kgs so I am using a figure of 350kgs as the total weight.

I do not want to use the Jayco / Coramal wire and winch system as they are susceptable to failure and will not handle this weight.

If anyone has any suggestions on a reletively simple and cost effective method to raise the roof 900 mm's I would appreciate your advice and input.

Yes I have considered parking under a tree and using a chain block, fitting a HIAB crane to the drawer bar and getting the "Men from Mars" to follow me around with a crane. All of these ideas were scrapped when I pulled the last strand of hair from my head.

Your help would be appreciated.

Regards and Happy Easter to All.
