Berkshire 390BH 340 vs. 350 HP

OK, I'm new to this whole forum network thing but I've spent the past few hours fascinated with all the knowledge and open advice. My wife has shot off a few questions and now I'm giving it a try. Here's my question: We are a family of 5 and I intend to trade a 2001 Georgie Boy Landau (gas) for a Berkshire 390BH (a decision solidified via this forum). I have no experience with a diesel, however. Currently we toad a 2005 Explorer Sport Trac which is quite a strain on the GB gasser; simple freeway overpasses kick it out of gear. So, I want to make certain that the next vehicle has adequate power to toad such a vehicle (estimated weight of 5600 lbs empty). I say empty because when we travel it's loaded down with bicycles, kayaks, razor scooters, etc. Do I need to opt in for the 350 HP with 750 lbs torque or will the 340 HP with 660 lbs be sufficient?

Since your Ford Explorer weighs 5600 lbs you would need to go with the larger engine since the rig with the 340hp/660 lbs can tow up to 5000 pounds while the larger engine can tow up to 10000 lbs.

I have never seen a gas Class A Rv that is rated for over 5000lbs towing to begin with so it's no surprise your old rig was having issues, you are very possibly overweight pulling that toad with that rig. No matter what the rig, I would think about a lighter toad, you and the RV will be happier.

Outside of that, always go with the bigger engine if it's an option. Better to have it and not need it than not have it and wished you had. Sure wished I had ordered the 2nd air conditioner on the roof!

Thank you for your advice. I double checked the weight of the Sport Trac and I was using the wrong number. I was using the GVWR which is 5840 but the curb weight is only 3600. So it is coming in beneath the limit of hitch rating. With this said however, it still placed an enormous burden on the gasser.
Think I'll go with the 350 which is rated for 10,000 lbs.

My Ford Edge weighs 4200lbs. I wish it were lighter, but I weighed it on a scale

You get an Allison 2500 transmission on the 340hp cummins that adds to limiting the tow rating. The 350hp gets you the 3000 transmission.

Bigger engine is the way to go. I see these guys rolling down the road with Cadillac Esclades and Ford Excursions strapped to the rear and I covet.. there I said it.. I covet thy neighbor... :-)

We have the 350 in ours and we toad with a Ford Focus which does a pretty good job. By the way you are going to love having the extra torque with the diesel compared to the gasser.

I drove the 340 HP from Lazydays in Seffner, FL to Wake Forest, NC pulling a 2005 Explorer Sportrac and never felt it behind me - amazing!

I believe that your Sporttrac weighs around 4000 lbs so you are under the max allowable towing weight. I have the same engine but at this point I do not plan on towing but I am happy to hear that the 340 hp was able to tow it with out any problems.
