Keep in mind that along with a toad, you'll need a supplemental braking system, a tire monitoring system and with the trending design of new gas stations that are RV unfriendly oriented, some planning will be needed for fuel acquisition. We've used toads in the past, but after many years of finally discovering who we are as Rvers, we decided that using the KISS mindset is the best for us. Breakdowns? We have Good Sam and it's worked for us on three different occasions...including two tows. Need transportation after a breakdown? Car rentals work for that as well as sightseeing situations.
The end result will be what you decide what will work for you....as all these fine folks who kindly responded to you have mentioned.
