Works for me. I've seriously considered a day cab for pulling my goose neck hay trailer around. Day cabs don't have much resale value. I looked at a day cab Pete with a Cat and 10 speed, twin screw, low miles for 22 grand.
One thing about using a Class 8 truck to pull an RV is, you don't ever have to worry about being over on an axle and put 'Private Carrier, not for Hire' on the side and no log book or DOT physical either. I think you still also need a Federal DOT number, I know I do with my 350 Ford because I use it to pull a hay trailer and I'm over 20K GCVW.
