Travelin2--- I know this isn't what you want to hear, but I'd leave the VX at home and get a little gas miser micro-car camp site beater that's front wheel drive and use a simple single-axle tow-dolly with the car's front drive axle on the tow-dolly itself.
Get something like a used cheapo Ford Festiva, Kia, Hyundai, etc. that doesn't weigh jack-sh!!!!!!!t, and is front wheel drive (for tow-dolly convenience). Save the VX for when you're at home. Your VX will last longer (parked at home), and your Motorhome will get better MPG, saving you money all-around. Just my 2-cents.
