I'd buy a Dakota version.
All you have to do is look at the second group of Dakota pictures to see the wheel and chassis setup on the Dodge and know that's the one you want.
The Ford wheels and chassis setup looks like it would suffer the same fate as many of the Toyota Motorhome's of the late 70's to early to mid 80's and have rear-end problems due to excess weight
on a rear-end with adapters for the dual rear conversion. There was a HUGE safety recall over this issue!
Based upon the picture of the Dodge Scamp motorhome above it's a V6 equipped Dakato Scamp and the year model must be 1990 or earlier. The 318 V8 was not available until the 1991 model year for Dakota when the grill,hood and front-end changed which resulted in a 3 inch extension of the front end allowing room for installation of the 318 V8. The 318 V8 Dakota was available from 1991 until the end of the first generation Dodge Dakota in 1996 and in the second generation Dodge Dakota's from 1997 to 2004. There were also some 360 CI Dodge Dakota's in the second generation production run. The 318 Dakota died with the production of the third generation Dakota beginning in the 2005 model year.
Anyone know what model years Scamp produced the "Motorhome" Scamps????
