Richard - you asked about gas vs diesel - and your truck/rv configurationis
similar to what we have used successfully. Note: our diesel was notturbo
charged and it did NOT have an aggressive pedal response anywhere alongthe
power curve. Patience and planning are sterling virtues.

Bottom line, we like both our gas and diesel tow vehicles. Biggest
disadvantage to diesel (for us) is some of the hideous places to refuel.I got
around the fuel pumps with diesel fuel on the handles (odor of dieselfuel on
my hand didn't come off after repeated washings) by wearing disposablegloves.

We quickly learned not to use diesel pumps where the macadam shinedor where
it was sandy (diesel fuel gets on the soles of shoes and then on thecarpet in
the truck). If the smell of diesel is perfume to you, then no problem.Our
diesel truck is airtight and well insulated so the smell and the noiseisn't
objectionable while rolling.

Of lesser inconvenience was searching for places around the continentto get
maintenance work done (always at a much higher cost than for our gasengines).

Plus, we needed to acquire another set of mechanical sensitivities.Luckily,
I have a mechanic friend who specializes in diesel suburbans. Thatmade the
acquaintanceship process with our diesel's needs occur quickly. And- we
could call him from any garage in any state and he'd talk with theirmechanic
about whatever problem we were currently experiencing. Twice, thatlittle
convenience led to the mechanic asking questions, getting a advicefrom our
friend and doing a better job for us than might have otherwise occurred.

Have you guessed yet? Every vehicle and the factors associated withit have
plus and minus features. My wife loves the comfy cloth seats in thediesel,
the fact of a front and back air conditioning and the clarity of thestereo.

For me, I love the rumble of dual exhausts, the aggressive pedal responseof a
finely tuned 460, the easy familiarity of a gas engine and no car paymentsfor
the last 20 years.

Bet this is more than you expected when you asked that question. Oh,well.
Bye for now, Terry
