Hi Steve,
As already stated weight will be an issue as off road vans are robust and heavy by definition and if your vehicle is limited to towing 2500kg that makes it pretty hard.
But it is not impossible.
If you are prepared to get a brand new van there are some issues you can consider to reduce weight on a custom made van (as we have just done). There are ways to reduce the weight of a van without compromising its strength or structural integrity:
(1) Look for manufacturers that use new materials such as sandwich panel. WE used this for our floor as it is much lighter than heavy marine ply and a far better insulator (imagine the temperature of the air just above the bitumen in summer...that is blowing up against your van floor)
(2) For all cabinetry in van use oak or mountain ash timber as it is very light and look good. Veneered particle board or MDF is very heavy. Same for door to shower...use lightweight acrylic rather other heavy material.
(3) IMO true off road vans do not have front or rear windows...this is where dust ingress is most likely due to the turbulence/vacuum effect when towing on a dirt road at speed. Also this saves weight....extra framing etc is needed for windows.
(4) Get one spare tyre for van only.... a tandem van can limp into the next town on 1 axle if need be ....1 spare means you will have to get 4 punctures before you come immobile. Carrying 2 spares is simply extra weight that is not needed.
BUT
Do not compromise on the important parts....we have 150mm galvanised chassis and heavy duty trailing arm independent
suspension with 8 shock absorbers.
Our 20ft 6 in van with full ensuite incl washing machine, 2 water tanks etc etc has a tare weight of only 2300kg and an ATM of 3000kg (but fully laden ours is about 2750kg).
Our Landcruiser can tow 3500kg but I have a self-imposed tow limit of about 85% of my capacity for safety reasons. Remember the vehicles tow limit is a MAXIMUM specified by the manufacturer and related to good road conditions in good weather. Most times you do not have the prevailing parameters to tow to your maximum capacity in my opinion (in the past 12 months on our travels I have seen 3 jack-knifed van accidents...all seemingly on good sections of road).
I also choose not to tow a van that is a greater weight than my tow vehicle. I know legally I can...but I choose not to.
These are some of the issues we dealt with 12 months ago when researching what van to get. After extensive research we choose to go to a manufacturers that would help us achieve a lighter van than otherwise would be the case without sacrificing the important bits or its off road capabilities. In the end we chose a Sunland Patriot and have just completed our first trip with it (7,000km). WE are very happy with it...especially its towing parameters.
Hope these comments help your deliberations.

(sandwich panel is 2 pieces of fibreglass with foam in between).
