I was going to go with a trailer, however after talking it over with some folks here bought the needed haredware (A fraction of the price of a trailer) to tow my 92 lumina APV 4 down... And I"m glad I did.
Only one real restriction on 4-down towing... Don't back up
Same restriction applies to dolly tows
And for, I suspect, 90+ percent of the motoring public... To trailers (it does not apply to me with a trailer)
(In fact it does not apply to me with a dolly either, as I have proven with a bit of help from U-Haul (their dolly)
I have not found the don't back up restriction to be a problem to date... Just pull the pins, lock in the axel, and drive the towed
OH, One very STRONG suggestion.... BRAKES:
Requrired in most all states in fact (texas being the exception and then only if the towed is under two short ton (4000 lbs)
#1 towed vehicle braking system by far is the M&G This is an air system, if your motor home has air brakes or air over hydralic it uses the existing air and controller, if not they provide an auxurally compressor. Limits: It will not fit on all vehicles and it's hard to remove
(It would not fit, for example, on my lumina)
#2 is the Unified Gear "Decelerator" system, this is an all electric pedal puller, you install it and leave it there, You do not remove it when driving the towed, just unplug from the tow vehicle.
Some folks like the Brake Buddy (It's a pedal pusher) but this has a box you have to remove every time you drive, and of course, can forget to replace when you tow, in which case it does no good at all.
Way down the list is another system (which is a lot like th brake buddy but is porportional,,, It tends not to work well on many vehicles due to power limitations... Suggestion is to avoid it)
I really like my Unified Gear system though
