I am guessing why you dont want to drive a motorhome. I am guessing that as a consultant, you want/need something smaller when you go on site. I am in the same business.
If I would provide a little more information, I think readers of this forum could give you some better suggestions.
1. What are you going to use as a tow vehicle? (make/model/year/engine)
2. What are you looking for in space/amenities/features on the RV, i.e. queen size bed, dry bath, must have space for a table and chair for work area, etc
3. What hookups will you have when you park, i.e. you would park at a campground with full hookups? will you be at your customer where you only have water? or only have electricity? This will determine what sort of holding tanks, fresh water tanks, generator etc you will need.
4. What is your budget?
Although it is technically possible to tow an old motor home 4 down (i.e. on its own wheels), remove the engine and transmission, set up the drive axle to free wheel or replace it, rig up a tow bar and (VERY important) set up a braking system, you are going to need a heck of a truck to do it safely. On top of that, I would expect (and this is not an insult to LEO's out there) lots of questions and stops by the highway patrol checking to see if your rig is safe.
In addition, most all of those wrecked motorhomes out there have been sitting for extended periods of time. That means they have not been maintained, they probably have leaky roofs, and the interior is rotting.
It sounds like you are a "hands on" sort of guy and looking to save a little bit of money. Let me suggest two different options:
1. Do some shopping for a used "U-Haul" truck or school bus with a good running drive train. Build living quarters in the back and tow your daily driver behind (either 4 down, dolly, or trailer) Do a little research on school bus conversions. Lots of good information out there on how to make your own motor home. You dont have to buy the biggest truck or school bus out there. Get one that fits your size.
2. If you have a 3/4 ton or larger pickup - look at truck campers. I got mine (see picture in sig) for $7500 and it is one if the bigger/heavier ones out there. Not suggesting that you get the biggest - just showing you that a decent one can be purchased at a reasonable price. If you have a SRW pickup you can easily take that on site at your customers during the day, then park at a campground at night.
