This (
www.mrsharkey.com) is one of my favourite web sites. Not only does it have everything you probably need to know about pusher trailers it also has extensive descriptions of some very interesting homebuilt RV's or motor homes. I've considered building a pusher trailer but it seems to make more sense to build a generator trailer to extend range. I think this idea of combining a generator with a slight pusher to compensate for the weight of the trailer may be an even better idea. This trailer is way too expensive for me to consider - but a good idea. The question for the DIY person like myself is where do you get a generator that can provide the kind of current needed but does not weigh 4,000 pounds?
