Hi Everyone. Well, after 15 years the RV-Dreams Community Forum is coming to an end. Since it began in August 2005, we've had 58 Million page views, 124,000 posts, and we've spent about $15,000 to keep this valuable resource for RVers free and open. But since we are now off the road and have settled down for the next chapter of our lives, we are taking the Forum down effective June 30, 2021. It has been a tough decision, but it is now time.
We want to thank all of our members for their participation and input over the years, and we want to especially thank those that have acted as Moderators for us during our amazing journey living and traveling in our RV and growing the RV-Dreams Family. We will be forever proud to have been founders of this Forum and to have been supported by such a wonderful community. Thank you all!!
There was a discussion the other day about this on another forum. One of the posters posted a spreadsheet that did some calculations to determine the HP needed to do a certain grade at a certain speed with a specified mass. Being the geek that I am, I converted that spreadsheet into a little web application to make it easy to play with some numbers. The web calculator is located here - Horsepower Worksheet
I can not attest as to the accuracy of the computations, as I took them directly from the spreadsheet. It is, however, cool to see how the different factors determine how much energy is needed.
Check the CAT RV web site and you find a very interesting article for download. It covers many of the same details and provides several good examples of what might be enough horse power.
