as o-t-r driver for 39 yrs. have seen many accidents due to under size vehicles & minimum braking capacity. tried it once with single axle open trailer, 2 hd's, no trailer brake, 99 tahoe v-8 (heavy veh), at obx,nc. car pulled out & I couldnt' get stopped, trailer pushing the vehicle. ended up going around the car on right shoulder. no accident, but new clean pants. for SAFETY of you & wife, I do not recommend this. I've owned 2 jeeps, a cj-7, grand wagoneer. as everyone else has stated, too short, lack of power & weight for stopping cap. I've seen such things as small vehicles towing campers, & various trailers swerving all over the road. once they start you can't stop it. usually jack knife or flip. NOT GOOD! last thing, as stated I drive for living & teach smith system defensive driving for trucking industry. I was pulling tanker full of H2O in richmond,va on I-95. pu with dual axle trailer, over loaded came by swerving from side to side. lost control, spinning around,throwing load all over road. ended up sitting broadside in front of me. I was able to swerve slightly into a left lane(as I was in far right lane) & drove thru his trailer. Couldn't get 80k truck with H2O sloshing around stopped. I grazed another veh with ICC bumper on my trailer. I could've hit him "dead"center &that's what he would've been, had I not seen it coming & tried to leave myself an out.Point is, he ended up with 7 citations, I got 0. Don't exceed what vehicle can do &brakes are a must, & should be checked prior to any trip,no matter how small. You talk about your wife & what she deserves. Don't "jeep" ordize her well being over something so simple. get a veh capable of doing what you need. buy a rubicon, leave bikes & rent when ya get to the coast, or look for something stable,with weight cap, & stopping cap. MHO sorry I got long winded, I just think of things in safety sense & from experience. We all make mistakes. just hate for one to be traumatic.
