We towed a Kia van using a lube pump for 'bout a year, before going to another vehicle (Ford Fusion hybrid) that doesn't need such.
As already said, you can expect the lube pump kit itself to cost around $1000. Unless you do the install yourself, you can figure on installation costing you another $500-1000 on top of that.
I will say that if you do plan on doing the install yourself, look over the installation instructions, and look everything over realll good under the hood of your vehicle. Make sure you're confident you can do it, complete all steps, before you start. Reason I say this is, this installation can get very, very challenging on some vehicles. On ours, I let the dealer do it, and am very glad I did! Technician had to take the motor and transmission mounts loose and raise them up briefly, to complete the install. There is no way in h*** I could have done that install! Took him literally all day to complete it, so I'd say he earned the 6 hours labor I paid for on that job.
๐Anyway, the lube pump itself, once installed and set up correctly, works great, and is a good solution to allow you to flat tow a vehicle you could not otherwise. Its a good choice if you want to tow a vehicle you already own, and want to avoid buying a new vehicle. Remco has come a long way with this product, and the monitor panel they use now pretty well eliminates many of the concerns there used to be with these pumps.
However, in your situation, where you're already buying a new vehicle anyway....JMO, but if I was in that situation, I think I would try to just buy a vehicle that is flat towable in the first place, from the factory, without having to mess with a lube pump. The lube pump will work, but it is just one more potential failure point, one more thing to worry about. Having towed vehicles both with and without said pump, I will tell you from experience, that not having to worry about a lube pump does make for more stress free camping. Its just one less thing to worry about.
Anyway, your $$, your decision obviously, but just want to throw that out there. Good luck and happy camping, whatever you decide.
